[cobirds] Lamar(Prowers) on September 2

Willow Valley Subdivision (private) in the AM:

BLUE-HEADED VIREO (1 bright, on the move, no photos)

Black-chinned Hummingbirds (3, one female/imm type had a tantalizingly green forehead but based on other characters I am leaving it in the black-chin column)


Fairmount Cemetery:

Townsend's Warbler (1 male)

Red-breasted Nuthatch (2)

Black-chinned Hummingbird (2, with male chasing off Eurasian Collared-Dove, also Townsend's Warbler, pursued other hummer: i.e. acting territorial). Question: could/would this species pull off another brood this late in the season?


Lamar Community College Woods (north end only, could hear chiggers giddy with anticipation in the bushwhacky south end):

Great Crested Flycatcher (1)

Warbling Vireo (3)

Wilson"s Warbler (2)

Bullock's Oriole (1f)

Blue Grosbeak (2-3)

PURPLE MARTIN (1f flyover traveling just above the tree tops going s to n in late afternoon)

Chimney Swifts (big flock of at least 30, silent, seemed "chunky", somewhat pale throated).  Do Vaux's Swifts pass over CO in autumn, and if so, during what time frame, what route, what style?  Are they known to roost with Chimney Swifts if and when they co-occur.  

Mississippi Kite (still a few around but main summer population appears to have moved on)


Texan Crescent butterfly (at LCC)


[As an aside, on my way down here yesterday, I had a roadkilled 9-BANDED ARMADILLO on US287 where it crosses Ft. Lyon Ditch roughly ese of Tempel Grove and about 5 miles north of Wiley.  To my knowledge there are only a handful of documented records of this creature in CO.  I found the remains of one many years ago in the Lamar tree dump e of Fairmount Cemetery and was told it had been discarded there after being hit by a mower when it ran out from the bushes by Parkview School, which is just north of the Lamar Swimming Pool at the north end of Willow Creek Park.  This area was recently famous, or infamous, depending on a person's success regarding the Swallow-tailed Kite.]
