[cobirds] 1st Creek @ GVR - Denver : Birds of Minor Interest

Starting a little before sunrise and birding for approximately three hours, I picked up 50 species along the newest and eastern-most portion of the First Creek Trail system.  

The Dunkirk Pond area (previous spot for the Yellow-crowned Night Heron and Blackburnian Warbler) was reasonably slow.  It did have the resident White-breasted Nuthatches, 3 Wood Ducks, a Great Blue Heron, Great Horned Owls, Red-tailed and Swainson's Hawks, American Kestrel, and a juvenile Black-crowned Night Heron.  A Cooper's Hawk was seen a little east of there.

The far western end of the trail, just east of Tower Rd had Gray Catbird, Blue Grosbeak, Broad-tailed and Black-chinned Hummingbirds, Wilson's Warblers, Lark Sparrow, Cedar Waxwings, and Red-breasted Nuthatch.

In between these two spots, in the Willow and Cottonwood area north of the bike path behind the row of houses just east of First Creek Park was were the fun was.  In no particular order, I observed Common Nighthawk, Nashville Warbler, Western Tanager, Clay-colored and Brewer's Sparrow, both Cassin's and Red-eyed Vireo, Sage Thrasher and a Blue-gray Gnatchatcher.

Annoying ID Alerts that you can ignore:  A Warbling Vireo was around a week or two ago, so pay attention to the vireos with eyebrows if looking for the REVI.  A MacGillavray's 
Warbler was seen yesterday, so the same advice applies for gray-headed yellow birds if you are looking for the Nashville.  Also, even though I managed to not see a single one today, the juvenile Chipping Sparrows should be around, so the spizella IDs are interesting.  

I think that covers it.  Have fun out there.
