First of all, don’t ask on the Telecaster board. Ask on wildlife, bird, vet, animal rehab boards. General guidelines, keep the animal contained, warm and dry, and give it water, air, food and the opportunity to go into light or dark areas of its enclosure as it chooses. You should only have to hand feed an animal if it's a baby. Immediately contact local certified wildlife rehabilitators. Do not contact animal control/Humane Society/whatever. They don’t give a ****, and mainly just show up to collect and kill animals. Wildlife rehabilitators are independent people who have been licensed by the state to rehab and release wild animals – not to "control" wild animals. They not only have more medical knowledge, but they also try a lot harder to actually save animals than do government animal control services. Then, start doing your research online. Chances are that even if you find a rehabber who will take the bird, you will have to float it for a day or two. Difficulty hopping could be something that’s easily recoverable in the grand scheme of things, and it is definitely worth trying in this case, in my opinion. I have rehabilitated and released far uglier birds from worse injuries.
