[cobirds] Pueblo Reservoir, Pueblo Co. 2/15
Nothing new to report, only one Yellow-billed Loon (not sure where the other one went), one Red-throated Loon, two Red-necked Grebes, seven Common Loons, and the adult Great Black-backed Gull all continue at Pueblo Reservoir, Pueblo County, this morning. Calm and cloudy conditions out on Pueblo Reservoir this morning, and there was no sign of the Pacific Loon that has been present most of the winter. Walked around Pueblo City Park today too, and couldn't find the juvenile Northern Goshawk, the juvenile and adult female Yellow-bellied Sapsuckers, the male Red-naped Sapsucker, or the Pygmy Nuthatches which were all seen last week (9 February 2022). Went to Mountain View Cemetery in Pueblo this morning as well, there were quite a few Yellow-rumped Warblers, the most I've seen this winter, over ten of them, and a Red-breasted Nuthatch, which have been pretty hard to find in Pueblo this winter.

Re: [cobirds] Flock of yellow-headed blackbirds drop mysteriously from sky in Mexico – video
It might be a part of a murmuration that got too close to the ground (possibly avoiding predator as already noted). Except for the blue sky background, I would wonder about a possible microburst or some other sudden downdraft, but without meteorological data from the scene, the predator avoidance seems most likely. Agree that it appears that most birds were able to move after grounding. As fast as they came down, a few casualties might be expected… Sent from my iPad > On Feb 15, 2022, at 10:52 AM, 'Deborah Carstensen' via Colorado Birds > wrote: > > > Extraordinary video of yellow headed blackbird‘s crashing from the sky.

It doesn't look like they died, it looks like they landed briefly then took off again.

Re: [cobirds] Pyrrhuloxia diet
Yesterday (2/14) I gifted the homeowner with about 10 lbs of jumbo white-striped sunflower seed that I was still hoarding from the grosbeaks that visited my yard last May and are expected to show up again this year. Will be curious to see if it takes a keener interest in those opposed to the black-oil seeds being offered presently.
