third of three recordings of this individual; from low inside short TDF on a rocky slope; same bird as prior recordings; song is ventriloqual, sounding to two of us as though possibly even a duet, with notes coming from different places, but listening to it this way sounds very normal, which I am sure it is; bad vehicle at 2:30; interval shortened at 6:24, at the end of which it took off, probably done with dawn song;

second of three recordings of this individual; interval shortened briefly at 0:30; it moved twice, perhaps in response to us, the second time returning to its original spot low in short, leafless TDF on a slope, away from the riparian; seem to be calls by another individual;

up to four birds interacting with vocalizations and chases, perhaps two pairs nominally on opposite sides of the arroyo; several moderate hiatuses between the better parts;

interaction calls accompanying physical interactions of three or four birds; some standard calls at the start, the 'good stuff' coming after about 2:55 with intense interactions after 3:40;

Same individual as XC278012. Pair seen, male having territorial disputes with Brown-crested and Ash-throated Flycatchers. Amplification, low and high-pass filters used in Audacity.

Probably same individual as XC278008, XC278009, XC278010, and XC278011 (same area as these detections on 15 June, likely a pair defending a territory).
