Hi Cobirders, Yesterday, while birding Rabbit Mtn. Open Space near Lyons, I observed an unusual looking American Goldfinch. Instead of having a yellow head with a black forehead it had a black face. The chin, sides of the face in front of the eye, and the lower forehead were black. I also saw the bird from behind and noted that the nape was pale gray. All other characteristics seemed consistent with AMGO and it looked to be in alternate plumage, as did all the other AMGO's present.
I haven't been able to find any information about hybridization in this species. Would anyone with knowledge of this subject care to comment? The bird was in a mixed flock with other American and Lesser Goldfinches and the exact location was: 40.24145, -105.20795.
