Carduelis pinus

I have been paying more attention to the details of the plumage of the large number of Pine Siskins that have been coming around in the last few days. I chose this picture because it shows fairly clearly how differently some of the birds are colored. The yellowish bird is presumably a green morph, supposedly very rare, although at least 25% of the birds here show definite yellowish feathers on their backs and breasts. We also have some Siskins whose wing feathers have a very large yellowish to off-white patch on them, at least four or five different individuals marked that way. See
