Ah poor thing.

In the morning, your vet can tell you Which vets in the area are licensed for wildlife. DO NOT take the bird to your vet; they have fits when you bring in the wildlife if they aren't licensed for it. A phone call will do.

Is it a fledgling? A young bird tryng to learn to fly and not quite there yet? Or is the injury so bad it CAN'T fly?? Can you tell?
