I was upstairs and heard a bang on the back window - another bird had flown into the dining room window. I quickly glanced over and saw it fall and I was horrified to see that it was my woodpecker!! He lay stunned on the snow drift behind the house. He was not moving. I went downstairs and looked out the bedroom window and got a closer look at him. He was not moving but he was breathing. His beak started to slowly open and close. He was alive but barely able to move. I have seen this before and they usually come around and, being a woodpecker, I knew he would make it. I continued to check on him - he slowly raised his head up and looked around then rested. The next time, his head was up and he was looking around and then when I checked again - about 1/2 hour after the accident, he was gone and back at the suet on the tree, good as new. But I bet he'll have a whopper of a head ache tomorrow. They are tough little creatures.
