In the process of filling out a Verification form for the Black-chinned
Sparrow, I note that the field guides show the species with a gray
breast and belly, the same color as the head. When we saw this bird
yesterday, it had light-colored breast -- cream or ivory -- that
contrasted with the gray head.
Do others agree with this observation? And if so, what does that say
about its ancestors?
