Take him to the vet! Remember that all animals in some way are helpless and they can't do everything for themselves!

this morning about an hour ago a little green bird hit our kitchen window and is sitting on the patio twitching his head back and forth. Almost like a jerk movement. He's been doing that for an hour. My thinking is he got possible brain trauma. I want to take him to the vet to help him. PLEASE HELP!
