Where do you live? I live in Norwich on Brigham Hill, and this morning I saw both a lone Pine Siskin and a somewhat ratty looking male Purple Finch, though I don't think they close. I have a female around too.. unless it's young, I'm not sure how to tell the difference.
An out of season...siskin at our feeders this morning (26-July) around 9. Followed shortly thereafter by a "ratty looking" purple finch...probably a young male as there was a hint of reddish on the wing coverts.
