[cobirds] Insect infestation and migrating warblers

I posted on Saturday about a feeding frenzy of warblers (Yellow-rumps and a few Orange-crowned and Wilson's and a Townsend's) that day. I noticed that leaves on the cottonwood trees where they were feeding had several yelllowish blotches on them. When I looked at the leaves closely it appeared

[cobirds] Palm Warbler - Coyote Ridge Natural Area - SW Fort Collins

Sorry for the late post. While mapping a prairie dog colony yesterday, I flushed a bird out of a lovely rabbitbrush stand that the pdog colony is slowly chewing away and destroying. I saw a flash of yellow on the undertail coverts and white on the outer tail. The bird landed close and I got a

[cobirds] Probable golden-plover, Panama Rez, Boulder Co., Sept. 25th

Hello, Birders. Just back from a lunch-break visit to Panama Reservoir, Boulder County, where I saw a not-too-close Pluvialis plover that I'm pretty sure was an American Golden-Plover. Never saw it in flight, though, and didn't hear it call. It was hanging out mainly near the west shore,

[cobirds] RMBO Barr Banding Station Report, 9/25/12

Today was slow and short. Not a lot of birds around, and we shut down early as it started to drizzle. A big bird day - first time I can remember having a Blue Jay and Flicker in the hand at the same time. Very noisy (both of them). Here's the breakdown of the 13 new captures: Red-shafted

[cobirds] Ruby-throated Hummingbird and Reddish Egret in Bent County

Birders, I had an immature male Ruby-throated Hummingbird at my feeder in Las Animas today. Birders are welcome to look, as long as they contact me first. I've been cloistered in my home office finalizing my annual report. I got a third-hand report today of a Reddish Egret at Lake Hasty

RE: [cobirds] Insect infestation and migrating warblers

SeEtta et al, This is very interesting. I collecting some of these, or something very similar, from Plains Cottonwood about a week ago at Roselawn Cemetery in Fort Collins. The makers of these pale circles are emerging in a container in my lab (aka kitchen). Yes, they are leafminers. Many

[cobirds] Probable Arctic Tern, Chatfield

Folks, While looking for Palm Warblers at Chatfield I found a sterna tern feeding on the lake. The bird was seen from the fisherman's pier and seemed to hang out in the middle of the lake, resting on buoys after dining on small fish (Gizzard Shad, again?). It was in breeding plumage and

Hi CObirders I saw an American Dipper in Clear Creek just east of Lowell Blvd (Adams Co). I looked downstream from the Lowell bridge itself. This is the location where Dippers nested in the spring. Last fall the first sighting was on Nov. 12, 2011. Bob Canter, Denver CO -- You received this

[cobirds] Crow Valley CG (Weld), Roselawn Cemetery (Larimer) and my yard (Larimer)

In retrospect, maybe I should have stayed home, as the best two species at Crow Valley Campground at Briggsdale (Weld) I also had today in my east Fort Collins (Larimer) apartment courtyard: Evening Grosbeak and Red-naped Sapsucker. Either there is one crazed Evening Grosbeak zooming around
