[cobirds] Blackburnian Warbler along Poudre, Fort Collins (Larimer)

I had a very brief look at a BLACKBURNIAN WARBLER north of Prospect Rd this afternoon.  I was on the west side of the river just south of the little bridge that crosses Spring Creek (used to be a sign here that said "Confluence Pond").  At this point along the bike trail there is a mowed lane that goes east over to a strange patch of pavement on the bank of the river.  This is between the Riverbend Office Building just n of Prospect and the place to the north we used to call the "Good Spot".  The bird was first heard in willows on the east side of the river.  It was moving from tree to tree n to s.  I got enough of a look for an ID but that's about it.  Doubt that this bird is chaseable.  Looked like a Townsend's Warbler in terms of yellowish, patterned head but back was striped and brownish with blackish wings with bold white wingbars.  Chip note struck me as "metallic" but somewhat subdued, perhaps by noise of river water.


Otherwise, the riparian areas both north and south of Prospect along the west side of the Poudre River were VERY slow.  Getting 30 species was difficult.  Did see a Buckeye butterfly amid all the Painted Ladies on rabbitbrush at Cattail Chorus hill.  Only other migrants were a Spotted Towhee, two Ruby-crowned Kinglets, three White-crowned Sparrows and one unidentified warbler I think strongly was an Orange-crowned.  Not even a Yellow-rump in autumn prime time.  Ho hum.
