ARIZONA SEASONAL REPORTS

SPRING 2008

Cooler than normal temperatures and late rains (and high-elevation snow) marked the spring season (1 March-31 May) in much of the state. Some species arrived later than usual, at least in substantial numbers, while there were many reports of lingering montane species in the lowlands, particularly Cassin’s Finches and Pine Siskins. A particularly noteworthy find was the Tufted Flycatcher in the Chiricahua Mtns. in the southeastern corner of the state. This tropical species has only been recorded in the United States three times before. Several regions reported larger than usual numbers of Red-necked Phalaropes. One important development not fully reflected in the reports is that this year a record was set for the number of young Bald Eagles fledged. From 30 nests 52 fledglings were reported, the last of which fledged in mid-June. Currently, there are 48 known breeding locations in the state, 44 of which were active in 2008 (AZG&F).

Our regional coordinators have assembled their reports for the spring season from the AZFO seasonal reports database, the Arizona-New Mexico Listserv, Northern Arizona Birding Forum, North American Migration Counts, and eBird. We encourage those interested in these reports to submit their noteworthy sightings directly to the AZFO database. Sightings that appear only on the listserv or other sites and are not on the AZFO site may be missed or otherwise not included in the seasonal reports. Moreover, the database offers a cumulative and searchable record of unusual sightings in the state. There are nine reporting regions, primarily based on biological and geographical criteria, which can be viewed on an interactive map. Species on the ABC Review List and observations of exceptionally large numbers of a species are in boldface. Many of them are hyperlinked to photos on the AZFO web site. Species and numbers underlined are exceptional reports for the specific region or season and some of them are documented with photos from AZFO’s online Photo Documentation gallery. The list of observers is at the end of the compilation.

Abbreviations used throughout the reports include: Arizona Bird Committee (ABC), Arizona Breeding Bird Atlas (Atlas), North American Migration Count (NAMC), National Wildlife Refuge (NWR), photographed (ph.), on the authority of (fide), and date + (birds seen through end of season).

Most of the published records from the LCRV appear in Birds of the Lower Colorado River Valley by K.V. Rosenberg et al (1991), which remains the comparison standard for reports from that area.

Rare but regular in spring along the Colorado R., one Pacific Loon was found on n. L. Havasu 9 March (ph. PD) and a second was found on L. Havasu near Site Six 30 March (ph. MMo). Casual after mid-April, two Pacific Loons in basic plumage were seen on L. Havasu from Pittsburgh Pt. 28 April (PL). An uncommon winter visitor and migrant through late April, a high of seven Common Loons were found on n. L. Havasu 27 April (PL). Considered rare through mid-May, four Common Loons were reported on n. L. Havasu 17 May with two remaining the following day (PL, BC).

Although a locally common winter resident, a single Canada Goose, either a late migrant or a nonbreeding individual, was found at n. L. Havasu 16 April (PL). There are few prior breeding records of Redheads within the LCRV, but this duck has bred at Beal L. Havasu NWR the past two years. A large group of 39, including females with young, were reported 30 May (DDe). Typically a rare and irregular winter visitor, a female Long-tailed Duck made an appearance on L. Havasu at Take Off Point 30 March (ph. MMo). Apparently, there are few if any March observations within the LCRV. Lingering late migrants, five Red-breasted Mergansers were seen on n. L. Havasu 17 May (PL).

A rare visitor, previously reported in 1993 and 2006 at Havasu NWR, a White-tailed Kite was once again observed at Pintail Slough 8 May (DDe). On 21 May, an adult Gray Hawk was observed soaring over the upper end of Alamo L. near the confluence of the Big Sandy and Santa Maria rivers. This individual entered into both Mohave and La Paz Co. air space providing an unexpected first report for both counties (SB).

Very locally distributed within shallow marshes of the lower Colorado R., two rarely seen Black Rails were detected 14 May at Castle Rock Bay, located along the Colorado R. immediately north of L. Havasu (HHo). Uncommon migrants in the LCRV, Sandhill Cranes have been seen on occasion flying north in small groups following the river. Twelve were observed flying over Beal L., Havasu NWR, 6 March and four tardy individuals were reported flying north over the same area 13 March (JA).

The early arrival of two Black-bellied Plovers, discovered among a large variety of shorebirds on a mudflat in Pintail Slough, Havasu NWR 13 March (DDe, HHo), was a welcome treat. There are few if any reports of this plover within the LCRV before late March. Red-necked Phalaropes are typically considered rare and irregular in spring (May) so an observation of nine on 27 April at n. L. Havasu was noteworthy (PL, BC). However, an unprecedented 3000+ Red-necked Phalaropes were observed flying north from n. L. Havasu during the early evening of 16 May. Early the next morning, only 100-200 remained on the lake, although throughout the morning the numbers increased to 1100 (PL, BC), suggesting these were likely new arrivals. These are likely the largest flocks ever reported in Arizona and rival the highest concentrations at the Salton Sea (Birds of the Salton Sea, Patten, M. A. et al. 2003).

Several species of northbound gulls were discovered this spring at n. L. Havasu, some of which were also observed as they made their way up the Colorado R. through the Havasu NWR. Four Franklin’s Gulls, considered rare and irregular spring transients, were seen flying over Pintail Slough 11 April (DDe, CCl). Several weeks later larger numbers of Franklin’s Gulls were reported at n. L. Havasu, with 24 on 28 April (PL). An even larger number of 135 was observed 17 May (PL, BC) with five to 10 of these identified as first-year individuals. The next day, 65 Franklin’s Gulls were seen in the same vicinity (PL, BC). Prior literature suggested the high count for these attractive gulls within the lower Colorado R. corridor was only six! Another rare spring migrant on the Colorado R. that was observed multiple times this spring was Bonaparte’s Gull. A count of 10 at n. L. Havasu 16 April (PL) was a high count. The highest known prior count for the LCRV was 12 in 1949. Another was observed 27 April in this same area (PL) and on 14 May one was seen in Topock Gorge (HHo). Then 17-18 May two Bonaparte’s Gulls were seen at n. L. Havasu (PL, BC). Not to be outdone, 19 California Gulls showed up at n. L. Havasu 17 May (PL, BC). The next day 30+ immature California Gulls were seen flying northward and 68 California Gulls were reported to be at n. L. Havasu (PL, BC). Apparently, there had been only one prior May report for this gull within the LCRV. With only four previously recorded Arizona sightings in the LCRV, the appearance of a Laughing Gull at L. Havasu near Pittsburgh Point 17 May (PL, BC) was a great find.

Four species of terns also appeared on the L. Havasu scene, much to the delight of many. Considered rare before mid-April, one Caspian Tern was found at North London Bridge 5 April (MR). Although a common fall migrant, Common Tern is seldom reported in the spring, however, this year an unprecedented 39 (including a single flock of 34) were reported 17 May at n. L. Havasu (PL, BC). Also at n. L. Havasu, an unusually high count of 48 Forster’s Terns was reported 17 May with 22 present the following day (PL, BC). Black Terns are considered rare transients after mid-May so one observed at n. L. Havasu 18 May was noteworthy (PL, BC). The Least Tern is a casual summer visitor on the lower Colorado R., with all previous observations only in June and July. So a Least Tern observed 18 May at n. L. Havasu was exceptional (PL).

Northern Saw-whet Owls are known to be highly migratory and notorious for straying far from their usual range. Following an observation during the winter season on Interior Rd. at Havasu NWR, another or the same individual was observed there 13 March (JA).

On 19 March an impressive high concentration of 100+ Clark’s Nutcrackers were noted on Mt. Trumbull, Arizona Strip (LHar, DVP). Irregular visitors to the Hualapai Mtns., one was also noted at Potato Patch 26 March (PMa).

Rarely reported in Mohave Co., a Downy Woodpecker was at a low elevation 19 March in Colorado City (LHar, DVP). A species of concern within the LCRV, the Gilded Flicker made several appearances this spring. Two, displaying courtship and pairing activity among the desert scrub, were observed near Oatman at the intersection of Silver Creek Rd. and Old Rt. 66 on 5 May (DDe, TT). Since 10 May a single Gilded Flicker has been hanging out with a Gila Woodpecker in the Havasu Heights area of LHC (KB). An early sighting of a Rose-breasted Grosbeak 30 March in Havasu Heights, LHC (KB) is noteworthy since it is typically a rare but regular migrant from mid-May through late June in the region.

A large number of Cassin’s Finches was an interesting find when 13 showed up at a feeder at Pine L. in the Hualapai Mtns. 10 May (PMa). Rare after mid-April the sighting of four American Goldfinches in LHC on 10 May (CB) was a pleasant surprise.

Following a wet winter, this spring was marked with several heavy snowstorms. Despite the inclement weather, a large number of lowland birds moved into higher elevations.

The continuing male Eurasian Wigeon at Continental Country Club was last seen 7 March (LHar, DVP). Mexican Ducks (Anas platyrhynchos diazi) are currently a subspecies of Mallard nesting primarily in se. Arizona south of the Gila R. Recently, individuals showing many characteristics of Mexican Duck have been reported in central Arizona. The status of these ducks in n. Arizona is largely unknown. Intergrades between Mexican Duck and "Northern" Mallards are becoming regular in Maricopa Co., but the extent of hybridization and individual variation are poorly understood. Such intergrades are probably rare but increasing in n. Arizona as the range of Mexican Duck could be expanding northward. One intergrade male and another male showing no obvious traits of typical Mallard were noted at Lower L. Mary 16 April (ph. DVP, LHar). These sightings are interesting but only tentative with the limited knowledge available on this complex. Photo documentation of these ducks in central and n. Arizona is encouraged.

Hooded Mergansers are scarce winter residents and transients in this area. A male was at Upper L. Mary 23 March (TLi) and a female was at WCP 16 April (DVP, LBH). One Clark’s Grebe was on Mormon L. with Western Grebes 28 April (ph. LHar, DVP, m. ob.). This species is generally a rare transient in the area, but has bred at Mormon L. While American White Pelican is a regular transient, a count of 200-300 birds at Rogers L. 17 April was notable (THld).

Cattle Egrets are rare in n. Arizona; an adult in breeding plumage at Mormon L. Village 28 April was unexpected (ph. LHar, DVP). Black-crowned Night-Heron is more widespread in Arizona but rare at high elevations. An adult at WCP 25 May was unusual (EM).

Zone-tailed Hawks, while common below the Mogollon Rim, are seldom seen above the Rim. Three in the Flagstaff area this spring is a remarkable count. One was observed at Rogers L. 18 April (DVP, LHar), another at MNA 30 April (ChL), and a third at WCP 26 May (EM). Rough-legged Hawks are regular but scarce winter residents in n. Arizona. A continuing adult male was seen at Mormon L. until 7 March (NG, m. ob.) and a lingering immature was present until at least 16 April (LHar, DVP, m. ob.).

Although Franklin’s Gulls are regular migrants in the region, they generally pass through in small numbers and are not commonly reported. This spring provided regular sightings, including a count of 19 at Rogers L. 18 April (DVP, LHar).

Several returning White-winged Doves have been noted in Flagstaff, reflecting its range expansion. A pair was reported 16 May (CFu) and a single bird 22 May (PKe). A female Ladder-backed Woodpecker was found in the Aubrey Valley northwest of Williams 22 March (LHar, DVP). This species is rare and local in this region of the state and seldom strays to extensive grassland.

Another species not regularly found above the Mogollon Rim is Vermilion Flycatcher. A subadult male was found at Johnson Tank near Bellmont west of Flagstaff 15 May (SB). The continuing adult Northern Shrike at Mormon L. was last seen 11 March (LHar, DVP).

Lucy’s Warbler is closely tied with lowland mesquite and riparian habitat and is casual above the Mogollon Rim. One was discovered at the East Rio de Flag (Logan’s Crossing) 3 April (JCn, ChL), and another was seen at Lower L. Mary 3 May (JC, LY, KM). A Prothonotary Warbler was present at Lower L. Mary 28 April – May 4 (ph. DVP, LHar, m. ob.). This species is casual in n. Arizona. Northern Waterthrush is a rare but regular migrant in n. Arizona; one was at Picture Canyon 28-29 April (DVP, LHar, NG). An adult male Hooded Warbler spent 6-13 May at Lonely Dell Ranch near Lee’s Ferry (VF, ph. JMal, fide JSp)

Summer Tanager is a common breeder in OCC and other lush riparian areas below the Mogollon Rim. It is a casual stray to higher elevations so a male on the NAU campus 6 May was probably a spring overshot (ErH). Black-throated Sparrows are found in appropriate habitat on the Colorado Plateau, but are rare at higher elevations. A bird at Mormon L. 4 April was unusual (DLam). The invasion of montane birds that began last fall in many parts of the state was especially noticeable in this region. Of special note were the large numbers of Cassin’s Finches reported through 28 April (NG, m. ob.).

Navajo and Hopi Nations

The spring season on the Navajo and Hopi nations was notably very dry in March and April followed by two or three powerful, wet storms in May. A few folks ventured to this vast desert region to try to find vagrants and other species at some of the migrant traps: Brian Gatlin made several trips to Gray Mtn. and Charles Babbitt and Bud Johnson made their annual multiday spring trip in mid-May to several sites scattered widely across the reservation.

Few people reported from the region during the peak duck passage in the first half of the season. However, two Red-breasted Mergansers were observed at Red L. 27 March (PKl). This species is infrequent but regular. A female Common Goldeneye was seen at CSL 9 April (CLR, BMar). This species is uncommon away from the Colorado R. There were 75 Western Grebes, which breed at only a handful of reservation localities, at Ganado L. 17 May (CBab, BJ). Common Loons appear regularly but in small numbers. Single individuals were at Pasture Canyon Res. 16 May and at Ganado L. 17 May (both CBab, BJ). American White Pelicans are occasionally seen on the region’s lakes and 20 were at Ganado L. 28 May (LN).

Compared to s. Arizona, it is remarkable how infrequently Great Egrets are reported from the Navajo Nation, but this spring there were three reports: one at Cameron 11 May (ErH), another at Pasture Canyon Res. 16 May (CBab, BJ), and one at Ganado L. 28 May (LN). Swainson’s Hawks were apparently more common in this region in the past, but are currently seen almost exclusively as migrants. One migrant was seen at each of the following locations 9 April: Highway 160 about 15 miles east of Tuba City and on Black Mesa at the Peabody mining operation (BMar, CLR).

A few shorebirds were reported. A Black-necked Stilt, infrequent but regular, was at CSL 23 May (CLR). A Sanderling was photographed at Ganado L. 17 May (CBab, BJ). Red-necked Phalaropes exhibit a pronounced mid-May passage and, in keeping with this timing, a vocal nocturnally migrating flock was heard passing over the rim of Black Mesa at Rock Gap 19 May (CLR).

The larger reservation lakes and ponds often attract gulls and less frequently terns. As elsewhere throughout Arizona Ring-billed Gulls are the most common. However, among the less frequently encountered gulls are Franklin’s, and this spring nine were seen at CSL 9 April, and one was there 23 May (CLR); 25 were also at MFL 17 May (CBab, BJ). Several Bonaparte’s Gulls were encountered: three 9 April at J7 Pond on Peabody’s coal mining operation on Black Mesa (CLR, BMar) and one the same day at CSL (CLR, BMar); another was at MFL 17 May (CB, BJ). Fifteen California Gulls were seen at CSL 23 May (CLR) where one had been noted several weeks earlier 9 April (CLR, BMar). Two were seen at MFL 17 May (CB, BJ). Two Forster’s Terns were observed at Ganado L. 17 May (CBab, BJ). Terns, in general, are relatively infrequent but regular at most of the larger reservation lakes.

White-winged Doves were for years only very rarely encountered on the Navajo Nation. The first report was in 1982. Since about 1997 it has become more frequent with a number of May reports. This spring one was at Cameron 13 May (BG), one at Ganado L. 17 May (CBab, BJ), and a third at Many Farms High School 29 May (LN). Downy Woodpeckers are fairly uncommon in this region and always of note. One was seen in Gambel oaks in Kinbiko (aka House Canyon), off of Long House Valley about 15 miles west of Kayenta 25 April (CLR), and a pair, suggesting possible breeding, was seen at Ganado L. 17 May (CBab, BJ).

Black Phoebes have increased markedly in the region in the past 20 years. A migrant was seen along the Little Colorado R. at Cameron 28 May (BG). This species breeds along this same river about 50 miles downstream of Cameron beginning at the permanent flow issuing from Blue Spring. Two were seen three miles below Blue Spring 8 May and three were there 15 May (CLR). A new early arrival date for Western Kingbird in this region was reported at Cameron 17 April (LHar, DVP).

An American Crow was seen at the campground at Canyon de Chelly 28 May (LN). This species breeds on the Navajo Nation primarily at higher elevations in the Chuska Mountains and Defiance Plateau. In the past 15 years a handful of breeding birds have been found at low elevation sites in cottonwood-Russian olive riparian groves such as this campground. A Red-breasted Nuthatch at Cameron 28 April and 5 May (BGa) was at an atypically low elevation for these dates.

Just a few noteworthy warblers were found on the Navajo Nation this spring. This seems to fit an apparent pattern of declining vagrant reports but with so few observers making regular trips to the region this conclusion is difficult to verify. A Nashville Warbler was seen at the seep at Cameron 19 May (JL). There is only one previous spring record of this species from the Navajo Nation. A female Northern Parula was at the Cameron store courtyard 18 May (NG). A cluster of Northern Waterthrush reports of one to two individuals came from the seep along the Little Colorado R. at Cameron 15-19 May (CBab et al.).

Summer Tanagers are quite sparse on the Navajo Nation, so a subadult male seen at Cameron 29 April (BGa) was a good find. This is also the earliest date this species has been reported on the Navajo Nation. An Indigo Bunting was seen at Cameron 28 April (BGa). This species is uncommon but regular at the widely scattered riparian sites across the region. Rufous-crowned Sparrow is found regularly but locally within the Little Colorado R. Gorge at the extreme limits of its range. Four were seen near Blue Spring about 50 miles downstream from Cameron 8 and 15 May (CLR). Black-chinned Sparrows were reported from the slopes of Gray Mt 28 April (BGa). This is the only spot this species is known to regularly occur on the Navajo Nation.

A Scott’s Oriole was reported along the South Rim Drive at Canyon de Chelly NM 29 May (LN). Despite suitable habitat (open juniper and pinyon woodland) this species was not detected during the 2003-2004 bird inventory of this National Park unit. It occurs widely but in low densities across the western half of the Navajo Nation. Hooded Orioles are sparse migrants/strays on the Navajo Nation so one in the bottom of the Little Colorado R. Gorge about 50 miles below Cameron 9 May was of note (CLR).

Yavapai

Compiled by Troy Corman, Roger Radd, and Carl Tomoff

Similar to the past winter, much of the spring season was unseasonably cool and even included a very odd mid-May snowstorm. This not only delayed budding of several high-elevation trees, but migration peaks for many species were also delayed by nearly two weeks. Exceptional numbers of late and lingering migrants were noted through the end of the season and into June.

Following the first nesting record of Canada Geese for Yavapai Co. in 2007, a pair successfully hatched five downy yellowish goslings by the early date of 20 April (JHi) in the Willow L./Cr. area near Prescott. The immature birds had developed black and white head patterns by late May (CT). A few ducks showing basic Mexican Duck traits are being identified annually in central Arizona in recent years—mostly in spring. If possible, such birds should be photographed and scrutinized for subtle characteristics suggesting typical Mallard parentage, such as pale tail edges and paler tertials. An intermediate male with both typical Mallard and Mexican Duck traits was noted at Page Springs 19 April (LHar). Although their status could be changing, Blue-winged Teal are still considered rare transients in the Prescott area. Therefore, observations of three 1 March at Willow L. (DI) and one at Watson L. 7 April (StB) were of note. Common Goldeneyes wintering at Prescott lakes remained into April: 10 were noted at Watson L. 7 April (StB) and another at Willow L. 12 April (BT).

Solitary American White Pelicans at Willow L. 23 March (CT) and 27 April (RG) were noteworthy for this casual transient in the Prescott area. There are so few records of American Bittern for the Prescott area that its status is considered accidental. Therefore, an excellent discovery was an individual at Watson Woods 22 April (MN). It was photographed 28 April (RG) and seen by other observers (fide CT) through at least 2 May (PN).

A Broad-winged Hawk was noted at Dead Horse Ranch SP 24 April (DVP, details pending). Although reported nearly annually within the Verde Valley drainage, particularly in April, this raptor is rare enough in Arizona that supporting documentation is strongly encouraged for review by the ABC. A casual spring migrant in Yavapai Co., a Baird’s Sandpiper was reported 11 May at the Sedona wastewater ponds (NG, TLi).

Following several lowland records this past winter in the region a Downy Woodpecker was noted 15 March within the upper Verde R. WA. Another Downy was observed on Mingus Mtn. 23-26 April (LHar, DVP) where this species is considered a casual visitor. Although considered accidental in the Prescott area, Brown-crested Flycatchers could be expanding their breeding range into the area. A calling individual was noted 3 May at the Granite Dells (CT). At least one Sulfur-bellied Flycatcher returned by 30 May to a site in the Sierra Prieta Mtns. southwest of Prescott (CT) where a pair nested unsuccessfully in 2006 and resided again through the summer of 2007. The Scissor-tailed Flycatcher, which paired with a Western Kingbird and successfully fledged young last summer in Camp Verde, had returned by 13 May (KM) and remained through the end of the season (ph. SR).

An American Dipper was noted at the Granite Dells 7 March (CT) and photographed the following day (StB, RT). This unique aquatic passerine is considered a casual transient to the Prescott area. Curve-billed Thrashers were confirmed breeding in the Prescott area for the first time 14 May when an adult was observed feeding a well-developed fledgling in Diamond Valley (JMg). A second pair feeding nestlings 28 May (CT) had fledged at least two birds by 15 June (JMg). Similarly, reports of breeding behavior from Curve-billed Thrashers in Cottonwood 25 March (SDo) supplement sporadic sightings over the last couple of years to indicate a small local population exists farther west in the Verde Valley than noted during the Atlas surveys.

A well-described adult male Chestnut-sided Warbler visited a residential area about 7 miles northwest of Prescott 31 May (BS). Although a few individuals of this warbler are reported each fall and winter in s. Arizona, spring records are very sparse. On 6 May, a female American Redstart, a casual to rare visitor to Yavapai Co., was observed at Tuzigoot NM (MA). Two very rare warbler hybrids were noted this spring in Yavapai Co. An apparent male Black-throated Gray x Yellow-rumped (Audubon’s) Warbler was observed on Mingus Mtn. 23 April (LHar, DVP, et al.). Then, an apparent male Grace’s x Yellow-rumped (Audubon’s) Warbler was discovered south of Prescott. It was suspected when heard singing 19 May and later confirmed 27 May and photographed 30 May (CT).

Another previously unreported hybrid combination was a likely male Western x Summer Tanager photo documented along the Kisva Trail in Red Rock SP. This attractive orange tanager with wing bars was first noted 26 May (BGa) and remained through the season. Likely the same odd tanager was noted at this location last fall. 

A northern-race (perpallidus) Grasshopper Sparrow was in the Cornville grasslands 19 April (RR). This easily overlooked species is reported less than annually in the Verde Valley. Casual transient in the region, particularly in the spring, a Swamp Sparrow was detected 11 March in Tavasci Marsh (BGa), and another at the recharge ponds in the Prescott area 9 April (SDr). A male Rose-breasted Grosbeak that returned to Granite Dells 7 May was still present in June (DKe). This is probably the same bird that has summered at this location for three consecutive years. Another male northwest of Prescott 14-15 May was photographed (PH) and a third was noted in east Prescott 23 May (TSh). Documentation for a male Baltimore Oriole photographed near Diamond Valley 7-11 May (TBee, SMo) had not been submitted to the ABC by publication time for this review species.

Following the previous season’s irruption of several montane species into lowlands of Arizona, including the Verde Valley, some species tarried into spring. Individual or small groups of Cassin’s Finches are sporadic low elevation winter visitors, but 60 birds present at a Cottonwood feeder 9 March (SR) was an extraordinary number. Small numbers continued at various valley locations into late April. Red Crossbills are casual in winter in low-elevation Verde Valley areas, so a pair visiting a Cottonwood feeder 3-4 April (SR) was tardy.

Typically an irregular migrant and winter visitor in limited numbers in Yavapai Co., individual Lawrence’s Goldfinches were noted at Tavasci Marsh and Dead Horse Ranch SP on 10 March (LHar, DVP). Three Evening Grosbeaks observed coming to an earthen livestock tank south of Seligman (JCv) 6 April was a good find for this rare and irregular visitor to Yavapai Co

The White Mtns. region experienced persistent windy conditions and cooler than normal temperatures through mid-May. This spring was also marked by an odd late May snowstorm. Localized movements of Cassin’s Finches and Red Crossbills from higher elevations that began during the fall and winter continued through the spring. Additional movements of Clark’s Nutcrackers, Red-breasted Nuthatches, Pine Siskins, and Evening Grosbeaks were also observed in some localities.

At Woodland L. Park in Pinetop-Lakeside, a Ross’s Goose was observed and photographed 8-10 May (ErH, AMar, PMar). Upon investigation, it was determined that this individual has been staying in the Show Low/Pinetop-Lakeside area since at least 2002. It was first seen at Rainbow L. (SSi, MSt) and later settled in with a flock of domesticated geese and ducks at Woodland L. There are dates of its presence at Rainbow L. on 12/13/02 and 9/19/03 (MSt). It has been at Woodland L. Park since at least 2006 (MSt, SSi, ErH). Ross’s Goose is casual in n. Arizona.

One female Wood Duck was found 6 May at Golf Course Rd. near Holbrook (ErH). Another individual, this time a male molting into nonbreeding plumage, was observed 19 May on Silver Cr. at Woodruff Dam south of the town of Woodruff (TC). Wood Duck is considered rare in n. Arizona. An unexpected sight was a male Eurasian Wigeon in a flock of American Wigeons near Nutrioso L. 4 April (ErH). The bird did not appear to be a hybrid. This species is casual statewide and there are only a few previous reports of this species in Apache Co. Common Goldeneyes, which are uncommon migrants in n. Arizona away from the Colorado R., continued to be observed early in the spring. Small numbers were noted at various lakes and ponds through 4 April (ErH), with a high of 13 noted at Nelson Res. South of Eager 5 March (PKl). A female Hooded Merganser was associated with a flock of Common Mergansers at Nelson Res. 5 March (PKl). This species is a rare transient in northern regions in the state.

Seldom-detected residents of the White Mtns., two calling Montezuma Quail were a great find at Wenima 4 April (ErH). Montezuma Quail are considered a rare local resident in the White Mtns. During the 10 May NAMC, an impressive flock of 56 American White Pelicans were seen flying along I-40 between Holbrook and Joseph City near Cholla L. (ErH, ElH). This species is an uncommon transient through the northern part of the state.

The Show Low/Pinetop-Lakeside area yielded some interesting raptors this spring, including a Zone-tailed Hawk seen 8 May at Woodland L. Park (AMar, PMar, ErH) and a Common Black-Hawk observed 10 May at Jacques Marsh during the NAMC (AMar, PMar). Zone-tailed Hawks and Common Black-Hawks are rarely reported above the Mogollon Rim.

Individual Willets were found migrating through, with one observed 7 May at CCR (TLi, NG, JLo) and one 8-10 May at Scott Res. in Pinetop-Lakeside (AMar, PMar, ErH). Willets are probably an uncommon transient in the region, but few reports exist for s. Navajo Co. Tantalizing reports of up to four Long-billed Curlews in the Springerville-Eagar area came in near the end of the spring season. With casual breeding records of this species here in previous years, the sighting of these birds through late May is suggestive of breeding. One bird was seen 6 May west of Eagar along AZ 260 and four birds were observed 8 May just south of the Springerville Municipal Airport (CWo, SW). Another bird was seen a few miles west of Eagar 31 May (MMo, GR, KR). Also of interest this spring were two Marbled Godwits at CCR (ZZ, TLi, NG, JLo). This species is a rare transient in n. Arizona away from the Colorado R (where flocks are not uncommon) and few records exist for s. Navajo Co. An amazing 82 Red-necked Phalaropes were observed at CCR on 19 May (TC). This is a very high concentration in n. Arizona for this rare spring transient. There are few reports of this species from s. Navajo Co.

Midway through the spring there were several sightings of Franklin’s Gulls in Navajo Co., beginning with one seen 27 April near the intersection of Zeniff Rd. and AZ 377 in the late afternoon. Two birds were present at Golf Course Rd. both 6 May (ErH) and 10 May (ErH, ElH). One bird was also observed on these same dates at CCR (ErH, ElH), although the birds present on both dates may not have been the same individuals. Bonaparte’s Gulls were observed earlier in the spring, with one encountered 3 April at CCR (ErH) and one at Luna L. near Alpine 4 April. This species is a rare transient in the northern part of the state. One California Gull was counted during the 10 May NAMC in Navajo Co. at CCR (ErH, ElH). California Gulls are uncommon to rare transients in this region.

During the beginning of May two exceptional tern species were found at CCR. A Least Tern was found flying over the reservoir 6 May (ErH) and a Caspian Tern was seen 7 May (ZZ, TLi, NG, JL). Least Tern is accidental in n. Arizona. Caspian Tern is casual to rare in n. Arizona, with few records for Navajo Co.

Even though it is a fairly common summer resident and probably a fairly common breeder in Navajo Co., there are few breeding records for Black Phoebes within the county. This spring one pair was building a nest on the wildlife viewing blind at Pintail L. near Show Low 8 May (ErH) and one pair was observed near an overhanging cliff on the northeastern end of CCR 19 May (TC).

A localized elevational movement of Clark’s Nutcrackers appears to have been continuing in the Eagar area, with one bird seen in a pinyon pine at a private residence 26 May and several birds previously seen in nearby Water Canyon south of Eagar 19 May (both DRo, GC). These birds were out of their usual higher elevation mixed conifer and spruce-fir habitats. A localized movement of Red-breasted Nuthatches continued throughout the spring in the Pinetop-Lakeside area, with some birders noting this to be the first time that at least one Red-breasted Nuthatch has been a regular bird in their yards (SSi).

With few reports in this region, a Crissal Thrasher was an interesting observation at McHood Park at CCR 7 March (ErH). This species is considered rare in n. Arizona and may breed at this location. Also, a sizable flock of Cedar Waxwings was observed at a private residence in Pinetop-Lakeside, with as many as 50 individuals seen at once 1- 7 May (SSi). Cedar Waxwings are an uncommon transient through n. Arizona.

One vocal Lucy’s Warbler was an excellent find in the cottonwoods at Wenima 4 April (ErH). This species is a casual to rare migrant above the Mogollon Rim and in the White Mtns. region. Sightings of Lucy’s Warblers in n. Arizona in recent years may point to a range expansion to lower elevation areas north of the White Mtns. on the Colorado Plateau. Another great find was a Northern Waterthrush along Silver Cr. at Woodruff Dam 19 May (TC). This species is a rare but regular spring transient through the state, with most records in early to mid-May, and photos were obtained.

A Slate-colored Fox Sparrow was an unusual find 4 April along the Powerhouse Trail at Wenima (ErH). Fox Sparrows are rare transients in Arizona, becoming casual after March. Another unusual sparrow was a breeding plumaged Harris’s Sparrow observed vocalizing near the footbridge over Rudd Cr. at Sipe 16 May (DRo). Harris’s Sparrows are casual in n. Arizona with very few reports this late in the spring.

Between 14-18 May an adult male Rose-breasted Grosbeak was observed in a yard on the east side of Overgaard (KF). Another male was also observed 25-26 May at a yard in Eagar (DRo, GC). Rose-breasted Grosbeaks are rare, but regular transients in Arizona with an increasing number of reports in recent years.

The winter irruption of Cassin’s Finches throughout much of Arizona continued this spring with extremely high numbers encountered in March, suggesting a peak in northbound migrants. At a private residence in Heber, the highest numbers observed in the yard at once were 86 seen 9 March and 94 on 20 March (ErH, ElH, BHo). Cassin’s Finches are typically an uncommon winter visitor and transient in this region. Another finch on the move in high numbers this spring was Pine Siskin, with 130 seen 10 May in Heber during the NAMC (ErH) and at least 1000 seen 16 May at Sipe (DRo). Pine Siskins are a common resident in the region, but these numbers were truly incredible for White Mtns. birders. An increased number of Evening Grosbeaks was also witnessed across n. Arizona this spring. During the 10 May NAMC, 21 individuals were seen in Heber (ErH).

Casual for sw. Arizona, a Neotropic Cormorant was reported at the mouth of the Bill Williams R. 16 & 27 April (PL). An early Whimbrel and a late Mountain Plover were observed in the Parker Valley 23 March (PL). An uncommon Black-bellied Plover and a very rare American Golden-Plover were observed together at a feedlot sludge pond on Vicksburg Rd. 27 April (PL, documented). A late Willet and an out-of-season Wilson’s Phalarope were found on Alamo L. 28 May (SB). A good-sized flock (for sw. Arizona) of 325 White-faced Ibis was observed south of Parker 23 March (PL). Twenty-five nesting pairs of White-faced Ibis were discovered in a mixed species breeding colony north of Poston 28 April (PL). This species has been confirmed nesting in the state only twice prior to this, at Cibola NWR in June 2000 and more recently at Painted Rock Dam. Two Glossy Ibis, casual in the state, were reported and well-documented: the first in an alfalfa field south of Parker 27 April (PL, BC) in a large flock of White-faced Ibis, and a second coming in to roost north of Poston 28 April (PL). A large colony of approximately 500 nesting Cattle Egrets was discovered north of Poston 28 April (PL). Three pairs of Snowy Egrets nesting in the same colony north of Poston 28 April (PL) may be the farthest north nesting record of this species in Arizona.

A rare Red-shouldered Hawk was reported at Cibola NWR 15 March (HD), but documentation for this review species had not been received by publication time. Casual to Yuma Co., two Northern Saw-whet Owls were seen and heard in Fortuna Wash from 11-17 March (LP, m.ob.)  One was inadvertently caught and released while mist netting for bats. An exceptional flight of 1000+ Lesser Nighthawks was witnessed at Imperial Dam on10 May (CH).

What was likely the only Thick-billed Kingbird in Arizona last winter was still present along the Yuma Main Drain 17 March (HD). A very rare (at least until this year) Brown Creeper was found at Mittry L. 10 May (MMc, CH). Warblers made an early push through Yuma Co. during the first week of April and then seemed to thin out. Many species were still trickling through the area toward the end of May, much later than usual. Uncommon and late, a Yellow-rumped “Myrtle” Warbler was reported at Wellton 15 May (PL).

Rare in Yuma Co., two male and one female Lark Bunting were reported on the Yuma Proving Grounds 2 April (SFi). A casual Cassin’s Finch was banded at Scott’s Well in Kofa NWR 23 May (CW).

A pair of Greater White-fronted Geese was reported at GWR 3 March (MSc) and the two that were found at Fountain Hills in late December remained until 5 March (JSm). The Snow Goose that wintered at the golf course in Casa Grande, remained until 27 March (m. ob.) and three were observed s. of Gillespie Dam 3 March (DPo). A Ross’s Goose was found at Arizona State University Research Park in Tempe 17 March and remained through the period (RDu, DFI). A male Wood Duck (rare after mid-April) was seen at Tres Rios 17 May (MHe). A male Eurasian Teal (a subspecies of Green-winged Teal, rarely seen in the U.S.) was discovered at GWR 2 March (PD); there has been at least one prior state report (in 1953) but this is the first to be physically documented, with photos. A Lesser Scaup (uncommon after the end of April) was reported at the Gila Bend STP 7 May (PL). A female Lesser Scaup was observed at Kearny L. on the very late date of 28 May (TC). A male Surf Scoter was found at Gila Bend power plant ponds 10 May (BGro) where it remained at least until 25 May (ph. CBab, SSt) and provided the first May record for Maricopa Co. The female White-winged Scoter that wintered at Saguaro L. was discovered there again 25 May (MMo), providing the second spring record for Maricopa Co. and the sixth for the state. A Common Goldeneye, observed at PRD 10 May (BGro), provided the first May record for Maricopa Co. A Bufflehead was reported at the Gila Bend STP on the late date of 7 May (PL).   

Three Wild Turkeys were discovered on Mt. Ord 10 May (DPo, KR, CR); the species is a rare resident of the high mountains in Maricopa Co. A Pacific Loon was discovered and photographed on Saguaro L. 30 March (KRo). This species is a casual winter visitor and transient with this the first March record for Maricopa Co. A Yellow-billed Loon, found and photographed on Tempe Town L. 20 – 24 May (DB et al.), represented only the second record for Maricopa Co., and the latest spring migrant for the state. A Common Loon photographed at Kearny Lake 5 April (MPe) was a rare migrant. A Neotropic Cormorant was seen in a new area – near Butcher Jones Beach, Saguaro L. 28 March (LHat,RWd). Courtship activity with sticks was taking place among Neotropic Cormorants at GWR 7 April (MMo), but no further breeding evidence was observed.

Individual White-tailed Kites were reported south of Gillespie Dam 8 March (MK), near Buckeye 30 April (TC), and on Arlington School Rd. 24 May (MHe). A Sharp-shinned Hawk (uncommon after the end of March) was seen at GWR on the late date of 18 April (MMo). A pair of Gray Hawks was discovered nesting at HRP 19 May (TC); during six springs and summers since 1993, one or two of these casual visitors have been reported at HRP. There was only one previous nesting record for Maricopa Co. The pair of Red-shouldered Hawks at HRP continued to be seen through the period (LHar, TC). A Rough-legged Hawk, a rare winter visitor, was observed flying over central Scottsdale 3 Mar (AMc). Individual Golden Eagles (rare residents) were reported near Camp Cr. 5 April (MV, BIs) and east of Goldfield Ranch 10 May (CFi).

Soras usually depart by early May, so of interest were the three that were reported on the NAMC 10 May (fide TC) and one at GWR 3 – 17 May (MMo). A large number of 100 Sandhill Cranes (irregular, rare winter visitors) were reported south of Gillespie Dam 7 March (DPo); interestingly the same number was counted in the same area on the same date a year ago.

Three Snowy Plovers were found 4 April in the section of Paloma Ranch where the species nested a year ago and by 25 April there were 10 adults, including displaying males, and five half-grown chicks; it was thought that nesting began in March. Numbers continued to be present there through the season (BGro). Individual late-staying Semipalmated Plovers were seen at GWR 17 May (MMo, NG) and at the sludge ponds east of El Mirage 23 May (CBab). The Northern Jacana that wintered at the golf course in Casa Grande, was last seen there 13 April (m. ob.).

Two Whimbrels, casual transients, were observed at Paloma 25 April and one was found at the Lower R. Rd. ponds, Palo Verde 10 May (BGro). A late Marbled Godwit was seen at the sludge ponds e. of El Mirage 23 May (CBab). Two Baird’s Sandpipers, rare in spring, were found at the sludge pond near Baseline and Palo Verde Rd. 30 April (TC). A large group of 21 Stilt Sandpipers, observed and photographed at GWR 17 May (NG, MMo), was especially unusual because the species is considered to be rare in spring; there was only one prior May record for Maricopa Co. Red-necked Phalaropes, rare in spring, were reported in larger than usual numbers in May. A group of 11 were noted below PRD 10 May (BGro) during the NAMC and individuals were seen at Veterans Oasis Park, Chandler 25 May (SF, JMan) and at the Gila Bend power plant pond 25 May (CBab, SSt).

One to two? Franklin’s Gulls were reported at GWR during April (MMo, RDi, HBon), one was seen flying over MCW 17 April (TC), and two were observed on the NAMC 10 May (fide TC). California Gulls are rare transients after mid-May, so four counted at GWR 23 May (MMo) was noteworthy. A Least Tern was discovered at GWR 5 May (JKo) and likely a different individual was noted there 22 May (MMo, BHi); the species has been recorded at GWR during May in each of the last three years. Another Least Tern was found at Gillespie Dam 16 May (PL). Individual Black Terns, rare in spring, were observed at Palo Verde 30 April (TC) and at GWR 23 May (DPe).

Although Eurasian Collared-Dove populations have rapidly increased in most small towns and rural communities throughout Maricopa Co. since their arrival in 2000, they have largely shunned the dense residential and highly urban area in the greater Phoenix area. That is until March and April, when individuals and pairs appeared and set up territories at many scattered residential neighborhoods in Phoenix, Scottsdale, and other cities (fide TC). A Ruddy Ground-Dove was found 21 March along Southern between 99^th and 107^th Ave. in Phoenix, in the same area where one was seen carrying nest material in years past (BGro). A Whip-poor-will, an accidental migrant in the lowlands, was discovered at PRD 10 May (BGro).

An adult male Broad-billed Hummingbird, a rare visitor to Maricopa Co., was observed 13 March at HRP (CM) and remained at least until 10 May (TC). A Broad-tailed Hummingbird, a rare transient at lower elevations, was seen in a ne. Phoenix yard 25 March (LHat). A male Rufous Hummingbird, an uncommon spring migrant, was reported near South Mt. 25 March (RFo).

The Lewis’s Woodpecker that wintered in Peoria remained until 4 March (BIn). Two Lewis’s Woodpeckers were found at Sunflower 28 March (RWd, LHat) and one was reported at Seven Springs 13 May (GL). Individual Acorn Woodpeckers, rare transients in the lowlands, especially in spring, were observed at HRP 10 May (TC) and at Tres Rios 10 May (MHe).

A Greater Pewee, an uncommon transient, was observed at Oak Flat east of Superior 4 May (PMo). A Dusky Flycatcher was observed at HRP on the early date of 1 March (LHar) and may have wintered locally. Another individual was reported at Paloma Ranch on the late date of 25 May (CBab, SSt). A Gray Flycatcher was observed singing at the top of a juniper in appropriate breeding habitat along Sycamore Cr. 6 April (PDv). An exceptionally high number of 20-25 migrating Gray Flycatchers were observed north of Carefree 19 April (TC). A pair of Vermilion Flycatchers, probably nesting, was seen along the lower Gila R. southeast of Buckeye 30 April; the species is a sparse nester along the lower Gila R. (TC). Tropical Kingbirds, one 10 May (TC) and two 16 May (MHe), returned to HRP where they have been nesting since spring 2001, the farthest north known site for them in the state. A Thick-billed Kingbird was found at HRP 10 May – back for the sixth consecutive year (TC).

A Bell’s Vireo was reported at Rio Salado on the early date of 1 March (TGa). A Gray Vireo, unusual in the lowlands, was found in a Scottsdale yard 19 April (JBar). Numbers of Western Scrub-Jays increased at Whitlow Dam to six 10 April and one was still present there May 10 (JBar). An American Crow, a rare transient, was discovered at Mesquite Wash 10 May (DPo) and provided the first May record for Maricopa Co. Common Ravens were found nesting near GWR 7 April, evidence of the species’ increasing presence in urban areas (MMo).

A Purple Martin, a rare transient, was photographed at GWR 23 May (BGri), one was observed at MCW 24 May (TC), and three were seen at Arlington WA 24 May (MHe). Several pairs of Barn Swallows were found nesting under low roadway culverts near Aguila during the NAMC 10 May (TC).

Two Brown Creepers remained at HRP until 21 March (MHe) and the Brown Creeper that wintered at Eldorado Park, was last seen there 2 April (JBar). Three Swainson’s Thrushes, uncommon transients, were recorded during the NAMC 10 May (fide TC), one found at GWR 13 and 23 May represented the 200^th species recorded at GWR (MMo, PDv), and one was observed at Spur Cross near the town of Cave Creek 31 May (BIs).

A Virginia’s Warbler, an uncommon transient in the lowlands that is not usually recorded after early May, was observed at Seven Springs Wash on the late date of 16 May (TC). The Northern Parula that wintered at GWR, remained at least until 8 March (RDi, MMo); another individual was found at Rio Salado 3 May (KR et al.). A Yellow-rumped Warbler was still lingering at Granite Reef 25 May (MMo). A Grace’s Warbler, casually seen in the lowlands, was found at BTA 10 May (J&BW), providing the first report for BTA.

A female Prothonotary Warbler was discovered at GWR (BGri), providing the eighth record for Maricopa Co. and the first in spring. A Mourning Warbler was discovered in a yard in ne. Phoenix 14 May (TC), providing only the third record for Maricopa Co. and the first in spring (documentation sent to ABC). MacGillivray’s Warbler is rarely recorded after mid-May, so of interest were the numbers found in late May: three at GWR 22 May (MMo, BHi), at least three along the Reach 11 Canal 23 May (KR), four at MCW 24 May (TC), one still at GWR 24 May (PDv), and one still at MCW 31 May (TC).

A female Hepatic Tanager, a casual migrant in the lowlands, was observed at Seven Springs Wash 16 May (TC). A female Summer Tanager was reported at HRP on the early date of 1 March (LHar) and a male was seen there 21 March (MHe); the species is not usually recorded before mid-April.

Two Green-tailed Towhees were observed at MCW on the late date of 24 May (TC). A Clay-colored Sparrow, a casual spring migrant, was discovered near the east side of the Agua Fria R., northeast of Southern Ave. in Avondale 6 May (TC). The “Slate-colored” Fox Sparrow that wintered in a Scottsdale yard, was seen there again 14 – 18 March (JBar) and one was found near ponds in the Agua Fria R. bed near Avondale 4 April (TC); the species is seldom recorded after the end of March. A Golden-crowned Sparrow was observed at Rio Salado 15 March (TGa) and the one found at Seven Springs in January, was still present there 19 April (DF, WT). Five Chestnut-collared Longspurs were observed near Southern and 99^th Ave. on the late date of 8 March (TGa et al.).

The Pyrrhuloxia that wintered at GWR remained at least until 20 March (PDv ph.). A male Rose-breasted Grosbeak came into neighboring yards in Hidden Valley, nw. Pinal Co. 13-14 May (ph. NL, JKe) in the same area one was reported last year in mid-April. Individual Indigo Buntings, rare transients, were found along the Gila R. near 99^th Ave. 14 May (TC), at Reach 11 Recreation Site 23 May (KR), at GWR 23 May (PDv), and at MCW 24 May (TC). The Painted Bunting that wintered at Rio Salado, remained at least until 16 April (PDv).

Cassin’s Finches continued to be seen in greater numbers than usual; flocks were reported at Sunflower during March and at least until 6 April (KR, RWd, LHat, PDv). A female Cassin’s Finch, observed near the confluence of the Hassayampa and Gila rivers, 30 April, was in an unusual habitat and elevation, especially so late in spring (TC). Individual Red Crossbills were heard flying over a ne. Phoenix yard 12 March (TC) and observed in a Scottsdale yard 15 April (JBar); eight were reported at BTA 15 March (ErH). Individual Pine Siskins, irregular visitors, were observed on Mt. Ord 28 April (RWd, LHat) and in a s. Phoenix yard 13 May (LS). Individual Lawrence’s Goldfinches were seen at MCW 21 March (TC), at BTA 18 April (RDi), and at HRP on the late date of 10 May, which suggested possible nesting (TC). The number of American Goldfinches at Tres Rios increased from one 21 April (MHe, RHa) to seven 6 May (TC); one was reported at GWR 2 May (MMo).

Gila

Compiled by Jeff Estis

Gila Co. produced some pretty good birding this spring, despite the low number of reports. The highlights were found on the AZFO field expedition to some of the drainages of n. Gila Co. 24-27 April. These drainages just below the Mogollon Rim drain melting winter snows from the high country and nearly always have some water in them. Historically American Dippers had bred in this area. One goal of the expedition was to determine if any were still present, but none were found. Although much of this area was devastated by the Rodeo-Chediski fire in 2002, a lot of the riparian habitat remains. More than 60 species were seen during the weekend.

A female Common Merganser was observed 5 May (JaMc) going into a nest hole in a cliff face along the upper Salt R. Common Mergansers are seen regularly in the area. Western Grebes, which have been nesting at Roosevelt L. since the late 1990s, are seen there regularly in large numbers. On 10 May, 435 were counted (JE). Three Clark’s Grebe’s were reported on the same date (JE). At least two pairs of Clark’s Grebes in pair bond rituals were reported from Roosevelt L. 12 April (DVP, LHar, WK). They have periodically been noted nesting at Roosevelt L. since at least May 2005 (AS).

A single Neotropic Cormorant was seen at Roosevelt L. 12 April (DVP, LHar, WK). Neotropic Cormorant, which has been expanding its range in the state, is still relatively rare in Gila Co., although it has been seen on occasion at San Carlos L. Double-crested Cormorants have nested at Roosevelt L. for many years, but now that the water level has been rising, increasing the amount of nesting habitat, the numbers have increased. More than 40 nests were observed 10 May (JE). Although Double-crested Cormorants have nested at San Carlos L. in the past (nests found in 1968) they were not found there during the Atlas surveys, so 50-55 active nests there 2 March (DJ et al) likely reflect good fish availability and the ongoing expansion of cormorants in the state.

A Bald Eagle on a nest with two large chicks near the Tonto Cr. inflow to Roosevelt L. was seen 12 April (DVP, LHar, WK). Unfortunately this nest and supporting branch, which had been in use for many years, fell soon after and the chicks were lost (AZG&F). A Willet was observed on a sandbar near the confluence of the Salt R. and Chalk Cr. 5 May (JaMc). Two seemingly out-of-place Least Sandpipers were observed at a farm pond along upper Canyon Cr. 26 April (JE). The 21 Franklin’s Gulls in flight and heading north over Roosevelt L. 12 April (DVP, LHar, WK) was an impressive number.

Noteworthy, was a Vaux’s Swift observed along AZ 88, just south of the intersection with AZ 288 (Young Rd.), 25 April (JY). This may be the first report of this species in the county. Downy Woodpeckers are seldom reported on the s. slope of the Mogollon Rim, particularly during spring and summer. Therefore three, including a pair excavating a cavity, were of note along the upper four miles of Canyon Cr. 26 April (AZFO). Another was noted in See Canyon the same day and another interactive pair was observed in a side tributary of Tonto Cr. south of the fish hatchery 27 April (AZFO).

One of the most noteworthy sightings during the AZFO field expedition were two adult male Magnificent Hummingbirds discovered near the group’s base camp in See Canyon (upper Christopher Cr.) 26 April (JE, ErH, et al. ph.). This was the earliest or one of the earliest dates reported for this species in the region. Two females were then observed 10 May during the NAMC at Pine Cr. (BIs), and another male was seen at a feeder in Pine 23 May (JE). Together these three sightings of five birds may be the most for a single season in the region. Magnificent Hummingbird is considered rare along the Mogollon Rim, with no confirmation of breeding, but perhaps this is changing. The only other area in Gila Co. where this species is seen with some regularity is at feeders among summer cottages in the Pinal Mtns. far south in the county.

The first Greater Pewees reported for the season along the Mogollon Rim were three calling in upper Canyon Cr. 26 April (AZFO). Violet-green Swallows are common in the Mogollon Rim drainages in the spring and summer, but the estimated 375 seen during a survey of upper Canyon Cr. during the AZFO field expedition, many of them nest building in dead cottonwoods, was a high concentration (26 April). Among the many passerines observed the same day were 90 House Wrens, a high number (AZFO). A bit on the early side, particularly for the Mogollon Rim country, Grace’s and Red-faced Warblers were noted constructing nests in See Canyon 26-27 April (AZFO). Large numbers (35+) of Cassin’s Finches continued to come to feeders in Pine into late March (JE).

Southeast Arizona

Generally this season was warm and dry in the region with the exception of a few storms that brought fairly widespread precipitation, including snow in the sky islands. Remarkably, Mt. Lemmon experienced its latest recorded spring snowfall ever on 22 May. It’s not clear if this short-lived snow affected high-elevation nesting species. Though there were some early wildfires in the Coronado National Forest, none of them were catastrophic or in especially sensitive areas. Migrants arrived in small numbers by the expected dates, but the bulk of migrants appeared to be delayed by 10-14 days compared to average, and overall numbers in many areas were considered unimpressive or low. Some observers noted a dearth of Greater Pewees in the Santa Rita and Santa Catalina Mtns., so this species bears watching. There were no reports of Rose-throated Becard this spring.

A Brant photographed at Willcox 29 April (PDd) was the third for the region; there are only about a dozen Arizona records overall. Greater Scaup is a casual to rare transient in se. Arizona; a male was photographed in Dudleyville 15 March (MMo). Late lingering ducks included a Canvasback at Benson STP 7-10 May (DSt), a Lesser Scaup at Willcox 29 May (DSt), a Bufflehead at Green Valley STP 31 May (MMa), and a very late female Common Goldeneye at Willcox 10 May (EW). A Red-breasted Merganser at San Carlos L. (Pinal Co.) 2 March (DJ et al) was casual. Three Neotropic Cormorants were at Arizona City 10 May (DJ) where they are seen regularly. Varying numbers (up to 25) of Neotropic Cormorants were reported at Patagonia L. (m. ob.).

Black Vultures have only recently been found regularly east to Douglas. Five were reported 18 March (EW). White-tailed Kites were reported from the San Rafael Valley (SMi, TC) and Picacho Res. (SSc). The first-of-season Mississippi Kite was in Dudleyville on the early date of 6 May (PKl). An adult Bald Eagle seen flying a mile north of Winkelman 25 April (DJ et al) was late for se. Arizona and might be nesting locally. During the Atlas surveys, Bald Eagles were found nesting near the confluence of the Gila and San Pedro rivers. A Northern Harrier was late at Sierra Vista EOP 18 May+ (EW). A Sharp-shinned Hawk soaring high over the Chiricahua Mtns. 18 May (DSt) may have been one of the sparse nesters there. Common Black-Hawks are regular migrants through the region and nest locally along streams, but a morning count of 42 migrants departing the riparian forest along the Santa Cruz R. at Tubac 19 March (RHo et al) was perhaps a high count for the state and highlights the importance of this corridor to neotropical migratory birds. Red-shouldered Hawk is a casual transient and winter visitor in the region; one was photographed in Patagonia 11-27 March (MB). As expected, it was of the elegans subspecies. The first migrant Gray Hawk of the season was reported at Tumacacori 5 March (MA). An adult Gray Hawk photographed in lower Madera Canyon 31 March (DD) was at an odd location in pine-oak woodland, though the species has been found nesting in similar habitat recently. The Short-tailed Hawk that wintered in central Tucson was last definitely seen 13 April (DSt). Apparently only one adult Short-tailed returned to Barfoot Park in the Chiricahua Mtns. this spring 15 April+ (HS et al). Other reports of this species went undocumented. Zone-tailed Hawks were reported in greater-than-usual numbers (m. ob.) Intriguing was a report of two pairs of Crested Caracaras displaying in the Santa Cruz Flats in March (MA); they are not known to nest in the area. At least one caracara was observed in the Santa Cruz Flats through 29 May (MPo, DJ) (in a location where two were observed through July 2007) and another was along Sasco Rd. 18 May (DJ). A caracara near Rio Rico and up to two at Tumacacori 12 March+ (MMa) were out of range but in an area where they have been reported in small numbers recently.

In the past Virginia Rail had been regular at Picacho Res., but lack of water there in recent years has limited habitat for them. One was present 6 April (DJ). Though they are numerous in wintering areas in the Sulphur Springs Valley, Sandhill Cranes are seldom seen elsewhere in se. Arizona; one at Tumacacori 12-21 March (MMa) was one of few ever reported in Santa Cruz Co. A Greater Yellowlegs in the Santa Cruz Flats 29 May (DJ) was casual on that late date. Marbled Godwit is a rare spring migrant. One was at Green Valley STP. 18 April (fide MMa). A Semipalmated Sandpiper photographed at Willcox 30 April (DSt) was in the expected time frame for this casual spring migrant. Four or more were reported there 4 May (DSt, CB). Even more casual, a White-rumped Sandpiper was at Willcox 20-24 May (DP, NP, R&RC). This is within the expected late May to June time frame for this migrant in Arizona. Baird’s Sandpiper is quite rare as a spring migrant in Arizona; several were reported from Willcox in late April and May. Stilt Sandpiper is a casual spring migrant in Arizona so four photographed at Willcox 17-18 May (KKe) were remarkable. Red-necked Phalaropes were more numerous than usual across the state, including in se. Arizona, with a high count of 50 at Willcox 18 May (DSt). An immature Heermann’s Gull was at Sweetwater Wetlands, Tucson on 28 March (SSc et al) and an adult Heermann’s Gull was photographed at a recharge basin in the Avra Valley 30 March (JH, DC). This casual wanderer from the Gulf of California has shown up in Arizona in most months of the year. Though still rare, Least Tern has become a more common migrant in recent decades. Singles were at Willcox 30 April (DBe, MSt) and 9 May (TC). Where these migrants are heading as they pass through se. Arizona remains obscure. Caspian Tern is a casual spring migrant; one was photographed at Patagonia L. 12-13 May (GR, DSt).

A rare visitor to the lowlands, a Northern Saw-whet Owl was enjoyed by many at Catalina S. P. 15 March-1 April (JLe, CCa) before it was reportedly killed by a predator. For the seventh consecutive year, there were reports of Buff-collared Nightjar from the Oro Blanco mine site near California Gulch 15 April+ (MPi, MSt). Estimates of the number of birds present ranged from one to three but only one was documented. Broad-billed Hummingbird is sparse in the Portal area; a male was photographed there 24 May (MD). White-eared Hummingbirds were more widely reported than usual but numbers were still small. Among those reported, individuals were photographed at the Beatty’s in Miller Canyon 6 May+ (TBe, BPf), at Santa Rita Lodge, Madera Canyon 6-9 May (CP) and at the Kubo in Madera Canyon 9 May+ (GB, LHal). A returning, banded Berylline Hummingbird was photographed at the Ramsey Canyon Inn 6 May+ (HD). This species is a casual spring and summer visitor to the area. No Berylline-like hybrids were reported this season. A Violet-crowned Hummingbird was in lower Ramsey Canyon 16 April (J&MH). They are rare away from Sonoita Cr. and Guadalupe Canyon. Among multiple reports of Plain-capped Starthroat this spring, written documentation was sent to the ABC for individual birds at California Gulch 22 May (PWe) and South Fork of Cave Creek Canyon 22 May (JLew). The east-side canyons of the Huachuca Mtns. remain the only reliable place for Lucifer Hummingbirds in the state. A male was photographed in lower Ash Canyon 28 March (BB), a male arrived at the Ash Canyon B&B on the same date (MJB, LWil) and a female arrived at the B&B 18 April (LWil). One was in lower Ramsey Canyon throughout April (J&MH). In Sycamore Canyon, 30-35 Broad-tailed Hummingbirds (all female) 17 April (DSt) was a high number of migrants away from feeders, indicating a “push” of migrants or abundance of food. A Belted Kingfisher was late along the San Pedro R. 29 April (EW); later yet was one at Fort Huachuca 2 May (DSt). The Green Kingfisher at Arivaca Cienega was last reported 6 March (m. ob.). Single Red-naped Sapsuckers in Cave Creek Canyon 18 May (DSt) and lower Madera Canyon 22 May (JY) were late migrants.

The Arizona rarity highlight of the season was without doubt the singing Tufted Flycatcher found along the main fork of Cave Cr. near Herb Martyr campground in the Chiricahua Mtns. on 5 May by Daniele Mitchell. It was photographed, recorded, and seen regularly there through 17 May (JPal, CBen, TGo, ON, GR) and reported only sporadically after that. There are only three prior U.S. records of this species whose range extends from east-central Sonora and s. Tamaulipas south to central South America. The only prior Arizona record is of a bird photographed at the mouth of White Rock Canyon, L. Mohave 24 Feb 2005 (See article and photos.) The breeding range of Tufted Flycatcher is in montane areas while in winter it sometimes descends to lowland mesquites, perhaps explaining the habitat disparity between these two Arizona reports. The first Western Wood-Pewee of the season was along the San Pedro R. 5 April (DBea). The first Dusky-capped Flycatcher was at Patagonia 27 March (MB) and the first Brown-crested Flycatcher was in Green Valley 14 April (BMas). Tropical Kingbird is an uncommon, local nesting species in se. Arizona whose range may be expanding. After nesting at Roger Rd. STP in Tucson for the first time last year, a pair returned there 11 May+ (DSt). Following reports of at least one bird present there last summer, a pair was found at the monastery in Saint David 24 May+ (MSt), a potential new nesting location between known locations along the upper and lower San Pedro R. The species was also widely reported from known locations this spring.

White-eyed Vireo is a casual transient and wanderer in Arizona. The individual found near Tubac last winter was reported through 1 April (m. ob.) Another was photographed at the San Pedro River Inn near Hereford 28 May (DBea). Gray Vireo is seldom reported (and even less often documented) in Arizona as a migrant and may be confused with Plumbeous Vireo by the unwary. One was found and photographed in Montosa Canyon, Santa Rita Mtns. 8-14 May (GB, KZ) and another heard at Peppersauce Canyon, Santa Catalina Mtns. 10 May (JY). Another casual transient, a Yellow-throated Vireo was recorded at San Bernardino NWR 30 May (RWe). A late migrant Cassin’s Vireo was seen in lower Madera Canyon 29 May (TC). A Ruby-crowned Kinglet at Tumacacori 17 May (LN) was a late migrant. Blue-gray Gnatcatcher is an uncommon nesting species in se. Arizona. A pair seen in the late stages of nest construction in lower Madera Canyon 3 April (MSt, MPo) was notably earlier than the dates found during the Atlas surveys. Continuing Black-capped Gnatcatchers were reported in the Santa Rita Mtns. at Proctor Rd., Chino Canyon, and Montosa Canyon, and in the Sonoita Cr. drainage at Patagonia L. SP and Patagonia Roadside Rest (m. ob.) The Rufous-backed Robin in Douglas was last reported 20 March (MC). The first two records of Aztec Thrush in Arizona were from the spring. There had not been another spring record until a female was photographed feeding in a Madrone tree in Huachuca Canyon 29 May (GF), almost 30 years to the day after the first record. Though it was a sparse spring for migrant waxwings, a flock of 10 Cedar Waxwings was on the late side 30 May in Patagonia (TC).

The latest migrant Orange-crowned Warblers were noted on 22 May in Madera Canyon (DT) and Tucson (MSt). A Crescent-chested Warbler documented at San Bernardino NWR 29 April (RWe) may have been northbound. Documented sightings of this casual visitor have increased in recent years. The Tucson Black-throated Blue Warbler was last reported 16 April (m. ob.). A Louisiana Waterthrush photographed at Tubac 20 March (BW) may have been the one that wintered there. Reports of Northern Waterthrush were down from recent years, with five reported 28 April-18 May. A Kentucky Warbler photographed near Kingfisher Pond in the San Pedro RNCA 1 May (JW, AW) was a casual transient. A female Hooded Warbler was found at the monastery in Saint David 24 May (MSt) and a male was photographed in a Willcox yard 23-30 May (PT). The latest Wilson’s Warblers reported were at Willcox (DSt) and Tucson (MPo) 29 May. The first-of-season Yellow-breasted Chat was early in Tucson 2 April (JBoc). A Western Tanager heard in Sycamore Canyon 17 April was early (DSt). Two Hepatic Tanagers in lower Ramsey Canyon 1 March (J&MH) were early as was one along Sonoita Cr. above Patagonia L. 26 March (RH). A Summer Tanager recaptured at Tumacacori 3 May had been banded there in 1997 (LN). The male Flame-colored Tanager returned to the Madera Kubo in Madera Canyon for another season 27 March + (CL, RH, GH). In upper Miller Canyon in the Huachuca Mtns., a male Flame-colored was found and a marginal photo obtained 18-25 April (JWo, BF); a male showing hybrid traits was photographed 26 April-22 May (DD). Hybrid tanagers have been reported and photographed in Miller Canyon for years, along with accepted records of apparently “pure” Flame-colored Tanagers.

Botteri’s Sparrows were found singing early again this spring, including one below Garden Canyon, Fort Huachuca 25-28 April (EW). A Clay-colored Sparrow was reported from Benson STP, 2 & 3 May (GB et al), and another was photographed in Portal 15 May (RT, GR). This species is a casual spring migrant. Late Brewer’s Sparrows included 10 at Willow Tank near Portal 17 May (DSt) and one in the San Pedro RNCA 19 May (EW). Several late Vesper Sparrows were along Stateline Rd. near Portal 4 May (DSt). Fox Sparrow is a rare transient and wintering species in se. Arizona. Two (of the expected Slate-colored form) were at Arivaca Cienega 14 March (MMa) and one persisted in the San Pedro RNCA until 6 April (EW). Casual visitors, two Golden-crowned Sparrows were photographed at Cave Creek Ranch, Portal 5-10 May (TGo et al). Both had been present since winter. Twenty caniceps Dark-eyed Juncos 3 May along the South Fork of Cave Cr. (DSt) was a large number for that late date. After that, singles were seen at two locations between Sunny Flat Campground and the Southwestern Research Station 15-18 May (GR, DSt) in the Chiricahua Mtns. A female Yellow Grosbeak documented at the Slaughter Ranch east of Douglas 5 May (RW, RAR) was earlier than most records of this casual stray to Arizona, which typically occurs from late May to mid-August. Rose-breasted Grosbeak is a regular spring and fall transient in Arizona. Among the dozen or so reported this season, up to two were photographed at Cave Creek Ranch in May (TGo, TC, DSt et al) and another was photographed at Ash Canyon B&B 4 May (PDd). The first Blue Grosbeak of the season was at Tubac 1 March (MMa). Indigo Buntings were reported a bit more widely than usual (m. ob.) An early Hooded Oriole was singing in a Tucson yard 11 March (DSt). A casual spring migrant, a male Baltimore Oriole was documented in a Tucson yard 2 May (DSm). Following a winter with good numbers present, Cassin’s Finches were reported into mid-May (m. ob.). Red Crossbills and Pine Siskins were also widely reported, including in the lowlands.
