I had a Pine Siskin at my bird feeder about a month ago and I had no idea what it was. I've never seen them before I asked Patrick from The Hawk Owl's Nest for help. He helped me ID it as a Pine Siskin. The Siskin spent a week or so at the feeder and then dissapeared - sounds like my Screech Owl ;-)
I just read the Stokes birding blog and they say that this is a good year for irruptive species such as:
Pine SiskinCommon Redpoll
The only one of these that I've had at my feeder is the Siskin, although I'd love to the rest of them. Have you had any of these guys at your feeders?
If these irruptive species are moving south because of a lack of food up north wouldn't the raptors follow? Does this mean that we may get some Hawk Owls and the like moving south?
