in flight

bird-seen:yes

playback-used:no

continued recordings of part of a wintering flock of 75-100 birds; 10-15 m up in cottonwoods; gusty wind; some minor cosmetic editing; mostly perched, but some birds in flight at times; interval altered at 10:10, after which more of the same, but more in flight after a limb broke under one part way through and many took off, circling around, up to 40 in view at once; no clear cut Commons to me, but a couple of deeper birds toward the end had me wondering vocally and visually; interval shortened at 15:39, with the most serious contender for Common in the middle, after at least 16:00 and especially 16:45, the bird giving boink-boink calls noted as specifically different (a Chihuahuan); some good recordings of wingbeats in this section; (this the third in a series of four with XC662792 XC662793 the first two);

a half dozen out of a wintering flock of 75+, in flight, others perched behind them in cottonwoods, taking a break from a morning at a food source in Sonora; interval shortened at 0:57 (better), mostly perched now; interval shortened at 3:30 for more good perched flock racket; a quieter period after 4:05 has some clearer calls; interval shortened at 8:54 (some wind problems at times); first in a series of four recordings, the last three being XC662793 XC662794 XC662795 );

perched bird, joined by another toward the end that did not add much; calling bird often leaned forward to make moaning calls; many loud typical calls, also a nice variety of quiet, guttural, clicking, snorting, and moaning calls, e.g., after 3:20 to 4:05; interval shortened at 8:23 (more quiet, conversational calls, then some loud calls, more guttural clicks); interval shortened at 10:13, in flight then; shortened at 10:24, featuring two perched birds with excellent guttural double clucks; first of two recordings, the other XC662811;

single bird in flight doing a circle around me, continued, landed, started doing various guttural clicking calls, joined by a second perched bird, both doing short, periodic, looping flights, landing again in leafless cottonwoods; I moved three times to get closer; one departed, the remaining one taking off, circling, landing, and then departing; a bird calling behind me flew by, landed, calling; then a string of 4 or 6 birds, singles or well spaced pairs, went by, calling in flight; either I did some extyra bad mic handling (always all too possible, and there is some anyway) or it does some kind of clicking noise, e.g., after 5:10 and 5:23 (I believe so for most of them, the signal not going below 200 Hz); interval shortened at 5:23 by 16 seconds, at 9:40 by 35 seconds; overall, some really fun calls;

four at a lagomorph corpse with a Turkey Vulture; about the highest pitched I have ever had around this area (juveniles?);

bird-seen:yes

playback-used:no

part of wintering flock of 75-100 birds, 4th recording focusing on a few birds perched in cottonwoods off to the side; more than one bird, some a little deeper, but overall like Chihuahuan to me; interval shortened at 2:36 for two birds counter-calling from different cottonwoods, one switching to guttural clicking, snorting calls; wind; interval shortened at 5:00, mostly in flight, bird after 6:15 possibly Common; interval shortened at 6:30 for perched Chihuahuan; interval shortened at 6:48 for different perched Chihuahuans with many little conversational calls, other birds in the background; interval altered at 9:42, after which Chihuahuan to start, ending with possible Common; flock is overwhelmingly Chihuahuan, but visually and vocally probably with a pair or two of Common mixed in; much wind; shortened at 12:39 for more apparent Chihuahuans, interval again at 17:02 for a puzzling pair; (this the fourth in a series of four with XC662792 XC662793 XC662794 the first three);

playback-used:no

at least two pairs in adjacent cottonwood trees, one bird from each pair primarily vocalizing, one emphasizing puck (e.g., after 0:40), and boink calls, the other with guttural clicking, also some regular calls; nice moan after 3:24, 4:24, 14:57 to 15:25; snorting rattle after 6:01; second of two recordings, the other XC662809); some of my best ever of this species;
