I thought I saw some on Saturday when I was hanging some laundry out to dry, but didn't get a close enough look to be sure.
Here's the photographic confirmation that Pine Siskins are in my yard (yard bird number 52). I haven't had Pine Siskins here for several years, but according to my migration chart, they're right on time by arriving in the third week of October.
What a cute little bird. The yellow wing markings show up pretty good in this picture, and you can kind of see a little bit of the yellow under the tail also. I hope they stay around for the winter.
