Rescue guy though he might have clipped a power line but we couldn't figure out how he made it as far as our yard.

I thought bird fight and he said that hawk are really really smart. Apparently there's some IQ scale for birds and hawks are pretty much at the top. He said they almost always retreat before they lose flight. Didn't rule it out completely but said in 12 years, he's only heard of it once or twice. Maybe this is thrice ??

And welcome to DU!

Shoulder muscle and wing damage too severe. He was never going to fly again and hawks aren't perch birds. As I understood it, the have to able to fly to feed. Even hawks and falcons are taken out to fly for food.

. But I guess we did our good deed helping this guy out with good intentions.

You tried, though.
