Colorful male American Redstart
I found this male American Redstart in a Colorado hotspot called Tempel Grove located just south of Negronda Reservoir and along a major irrigation canal. Unlike much of this and other irrigation canals there is a lot of vegetation, both trees and shrubs, that the Tempels had to fight the canal company to keep (irrigation companies routinely destroy vegetation along canals to reduce water loss). Melody Temple, who is now deceased, loved birds and her husband has dedicated the birding trail area along the canal that is generously open to birders in her memory.
This male American Redstart in his striking breeding plumage was feeding in some of the trees just off the canal (currently empty). It has what looks like a fly in it's beak in the top pic. The only other warbler I found there was a Hooded but I only heard it sing twice and did not find it visually. SeEtta
