Carduelis psaltria

We have seen the numbers of Lesser Goldfinches increase quite a bit in the last week or so. Like their cousins the American Goldfinches,
they frequent the seed feeders. At first, I found it a bit hard to distinguish between the female American Goldfinches,
the female Lesser Goldfinches, and the pre-molted male American Goldfinches. But, now that I am a bit better trained,
the Lesser Goldfinches are noticeably smaller, and darker. The males, as shown here, have dark olive-colored backs and
a much larger black cap than the male American Goldfinches.
