This low quality recording is for ID purposes only. Thirty seconds of the recording where no vocalizations occurred were spliced out and are indicated by the fade out/fade in. 80 Hz, -12db hi pass filter set on the recorder, and an additional 80 Hz, -16db high pass filter added in processing. Additional notes are in the recording annotation.

It's not clear (at least to me) whether this is an early migrant or a local breeder. They likely bred here in the past, and I have recorded them here during the breeding season (July 2nd) in the recent past. There are still plenty of cottonwood, oak, and sycamore stands providing suitable habitat, but much of it is now blocked off to visitors at Mission Trails, so their presence could be under-reported.
