1) What species or recordings are posted?
We are interested in recordings of all species that
occur in Arizona. Unlike commercially available
recordings, this site emphasizes recordings made in
Arizona to represent local dialects. We therefore
prefer recordings made in Arizona, but for rarer species
we will accept recordings made in adjacent areas such as
California, New Mexico, Sonora or Chihuahua.
We are interested in documenting regional or
subspecies variation in vocalizations. Therefore
we want to post more than one recording per species.
If you have a recording of a species that is already
posted but it documents another vocalization or is from
another region of the state, we are very interested in
posting such files.
2) What are the file size and type restrictions?
All files submitted must be in MP3 format and usually
no longer than 90 seconds.
Files should be encoded 128 kbps, 44100 Hz, Mono and
be no larger than about 1.5 Mb
We prefer recordings that maintain the natural song
rate intervals. If the intervals are unusually
long and you shorten them, please note this when

attachments directly to the

concerned with how your files might be used, it is
probably best not to post them on the Internet.
