I just got off the phone with St. Francis Wildlife and they said my little hummingbird is doing well this morning! They fed him all night and he is still eating this morning. They are also keeping him warm. He is bobbing his head kind of funny though, so they think he might have some neurological damage and probably crashed into the window. They are giving him a 50/50 chance of surviving, so I'm keeping my fingers crossed for the little fellow!
