This bird has been hanging out on the thistle sock the last few days, or at least that is when I've noticed it. It is always with the Goldfinch, and it is the only one I've seen. Is it a Pine Siskin? That is the only one I can come up with, but I've never seen one of those before, so I'm not sure! It is a little more orange looking in person. I've got photos from other angles, but they are a little blurry. I will try to get better pictures to post. Any suggestions, if it isn't a Pine Siskin, would be most appreciated!
