[cobirds] Lamar on Tuesday 20October
Learned lots of interesting things about psyllid foraging this morning at Riverside and Fairmount Cemeteries. The other day I said I thought the delayed emergence of the adult psyllids from fallen leaves would allow them to escape migrant bird predation. That guess might have been in error. Today I watched a flock of 350+ Common Grackles with a very few European Starlings land right under a hackberry with lots of fallen leaves and begin flipping them over like frenzied solitaire players. Either they knew adult psyllids might be there, or they were just flipping and adult psyllids happened to be what they found in greatest abundance. Very interesting, whatever was going on. At Fairmount Cemetery today: Yellow-bellied Sapsucker (FOS, juv. female) mostly checking out junipers Nashville Warbler (1, I would say western on the basis of incessant tail-wagging) with yellow-rumps, feasting on hackberry psyllids gleaned from leaves/bark or pursued into the air after flushing Dave Leatherman Fort Collins --~--~-~--~~~---~--~~ Colorado Field Ornithologists: http://www.cfo-link.org/ Colorado County Birding: http://www.coloradocountybirding.com/ You received this message because you are subscribed to the Google Groups Colorado Birds group.

[cobirds] Golden-crowned Sparrow, Tunnel Dr., FreCo
This morning I found a Golden-crowned Sparrow at the end of Tunnel Dr. in Canon City. It was in brush alongside the dirt road that goes down to the brick pump house. It's almost certainly the same GCSP that was here the past three winters, staying through the end of March. I haven't seen any of the Rufous-crowned Sparrows here yet this fall. The trailhead parking lot is closed for repairs due to a flash flood. A lot of the brush and cactus vegetation around the parking area has been washed away or bulldozed. The parking area has been enlarged to the west and a catchment basin constructed in the area west of the parking lot. I mention this because this was probably the most intensely birded brush patch in Fremont Co. Now much of it is gone .. and they're not finished.

[cobirds] Yellow-throated warbler, Estes Park
CObirders, On a bike ride around Lake Estes today, Julie and I stopped to watch a small group of warblers in the Matthews/Reeser Bird Sanctuary. Among a handful of yellow-rumps and one bright male Wilson's warbler was a gorgeous yellow-throated warbler. A buffy wash on the underparts suggests it was a first fall bird. I didn't get an ID look at the bird on first sighting, so we spent an hour chasing the flock Attu-style, i.e. on our bikes. Seen first at the east end of Warbler Alley, we followed the birds east to The Narrows nearly to the bridge over the river and then back all the way to Night-Heron Pond, where Julie found the bird again for me. We had five minutes at close range with it, and then it was gone again. It was not relocated by a group of birders later in the afternoon. It was a sneaky bird, hanging around the yellow-rumps but not with them. It seemed to like better the company of a couple of chickadees associated with the flock. This is the second record for this species at Lake Estes since comprehensive records began in 1996. That was a May bird that several locals got to see. Julie and I were at another part of the lake and hustled over, but we missed the bird by about 15 seconds. It was not seen again. A nemesis bird in the making and a close call for me today of keeping it so.
