[cobirds] A short report from Cheyenne and Kiowa counties 2/14

DFO's outing to Cheyenne and Kiowa Counties on Monday 2/14 had the Common Redpolls in Cheyenne as a highlight, which I posted on from the field that morning. But the flock of about 35 redpolls were at CR 20, not 22 as I had posted that day. I've attached two nice pics taken by Gary Witt, including redpolls flying! Here is a link to our checklist with some other photos. 

eBird has no other records of redpolls from Cheyenne County, and it seemed from the CFO county birding page that there were none, so perhaps this was the first county record. 

After encountering so many Rough-legged Hawks (and other raptors) the prior week in Phillips and Yuma, we were surprised by the paucity of raptors on our transects through Cheyenne and Kiowa. There we had just 4 Rough-legged Hawks as opposed to 27 in the two northeastern counties, And those were our only 4 identified buteos the entire day; we even missed Red-tailed Hawk despite driving over 350 miles in eastern CO!  Open field birds like Horned Lark and Lapland Longspur were fairly sparse (224 and 47 on our 18 complete checklists, for example). Also missing for us were Golden Eagle, Ferruginous Hawk and Prairie Falcon, all to be expected I think, on such an outing. 

At Neenoshe Reservoir we found great numbers of geese, with an estimated 25,000 white geese  (mostly Snow) and 13,000 Canada/Cackling.

[cobirds] GHO

When your favorite tree & hunting areas are burned you have to set up a new home.
A flower pot is as good as anything! 
This is on a neighbor's back deck. There is one egg in the pot. Fortunately the owners are willing to let it be & give it space. They have been dived bombed once by the mate.

I've noticed our neighborhood Red-tails are still around but now also hunt in a neighborhood where there is less burn area. I saw the neighborhood Kestrel a few days after the fire but have not seen it lately.

Tracking Birds From The Great Plains to The Chihuahuan Desert

Grassland birds are among the most imperiled group of birds in the United States. The Motus Wildlife Tracking System (Motus) is a network of automated radio telemetry stations that offers an effective method to explore animal movement. Join Avian Ecologist Matt Webb to learn more about how Bird Conservancy of the Rockies is developing a network of Motus stations and tagging birds across the Great Plains and Chihuahuan Desert to study the movement behavior of grassland birds. This network will allow researchers to gain a new understanding of how grassland birds move throughout their full annual cycle.

[cobirds] Re Yellow-headed Blackbirds

Hi

I remember years ago being in central Mexico, late winter-early spring, where  enormous flocks of Yellow-headed Blackbirds wintered. The spectacle was made even more dramatic, because of the tendency of blackbirds to separate into  same sex flocks. So image a huge flock, containing many thousands of male Yellow-headed Blackbirds all swooping and swerving, with the flock size constantly shifting and re-formulating  in size. From a distant a flock can appear like a huge yellow ball, because of the dominate coloration of the yellow on head of males. It's is a visualization that I'll never forget.

Re: [cobirds] Flock of yellow-headed blackbirds drop mysteriously from sky in Mexico – video

Feb. 2005, I planned to spend one night in Cuauhtemoc Chihuahua as I traveled by bus to Creel.  I before dusk I went to the plaza and experienced an amazing spectacle.  The sky was black with thousands of yellow headed black birds coming to roost in the plaza trees for the night.  The sound was deafening.  Locals said this was a daily occurrence.  I spend another night so I could watch the birds come in from the surrounding fields from the roof of my hotel.

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

The Reuters Twitter video included in the provided link does indeed show what appear to be dozens of dead Yellow-headed Blackbirds on the street...

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…
