Common Redpoll has become common at the Aerie

The Common Redpolls have hit the Aerie in force. We've a flock of around 50 of them flitting around most of the day. There are two or three that I suspect might be Hoary Redpolls (slightly smaller, paler and less striped along their flanks) but they're moving about so much that it's difficult to be 100% sure. (A couple of years ago, I could be sure. One of the little buggers crashed into the window and broke its little neck. Odd thing is that seven years earlier it had been banded up in Quebec by and "expert" who labeled it a Common Redpoll when it had absolutely no striping and was white as a ghost.)

Anyway....Here's a small sample of the invading horde from the north.
