This is a Hairy Woodpecker, a species of bird found throughout North America. They can often be found pecking at trees in order to find the wood-boring bugs that are their preferred food source. This little one was admitted to us because she was unable to walk and had a head tilt. Often in cases where birds are displaying neurologic symptoms the first thing we think of is that they hit something head on. Birds often strike windows while flying, because they see right through the glass and assume that they have a clear flight path. After a few days of rest and some anti-inflammatory medication however, she is doing much better, and should soon be ready to go back to the wild.
