After posting a rather long post on my other blog about how to identify downy and hairy woodpeckers, I am now stumped. I think this is a downy but I'm not sure. If it is, it is a male demonstrating aggressive behavior that I usually associate with hairy woodpeckers. Oh well.
UPDATE (3/30/2011): it is a downy. But now, I find I have contradicted myself when I said that downy woodpeckers don’t have the intense eyes that hairy woodpeckers have. Oh well.
