Who Are You?

I thought my feeders were being visited by a new species of bird, but then I looked up "House Finches" in my Audubon book.  According to it, the yellow and orange ones are immature males and will become more red as they get older.  I've been feeding birds for years, but this is the first time I've ever seen the yellow and orange ones.  I guess I'm not as observant as I thought... 


I wish they'd stay yellow and orange, I think they're gorgeous!
