Lesser Goldfinch

Spinus psaltria - Common in flocks in same or drier habitats than American Goldfinch. Breeds to 7,500 feet. Both a black-backed and a green-backed form occur. Males of both races are easily told from American by the dark rump and, in flight, by the large white wing patch. Females are told by lack of contrast between back and rump. Two were enjoying our feeder in the yard.
