Black Swift (Cypseloides niger), Ahwatukee, Maricopa County
This Black Swift was
discovered dead on the ground by Roberta and David
Chorlton on 25 September 2017 and photographed by Troy
Corman on a later date
It appeared to have been dead for several days as it is desiccated and damaged by ants. Troy Corman obtained the specimen
(to be deposited in a museum) on 28 October 2017 and took the photos being submitted.
there are 8 accepted sight-only records of Black Swift
for the state, this will be the first physical evidence
for Arizona (no prior photos or specimen). Given its
breeding range to the north of Arizona and its status in
surrounding states, this species likely migrates annually across Arizona, but most may migrate at too high of altitude to be observed regularly in the state.
and all slaty-black swift with broad tail and broad
based wings. The white edgings to the feathers ages this
as a hatch year. The size and white above the eye rule
out potential vagrants from outside the United States.
