This little fellow hit a window this morning. When I first picked him up he struggled for a few seconds and I thought it was ok and was going to fly away but then it settled down and would close it's eyes and rest and then look more alert and look around. I carried it around in my open had fro 20 minutes talking to it as it regained it's strength . Finally it flew a few feet into a fir tree and was on it's own again. I haven't checked to see what breed it is likely a Warbler of some sort.
