I get red shouldered hawks flying with my planes quite a lot. They've never bothered them. I did have one stoop from out of nowhere to check out the plane, but he pulled-up well before he hit it.
The only time any wildlife interfered with my flying was when a mockingbird attacked my Blade CP Pro while I was flying in the back yard. Of course there wasn't much left of both the bird and the 'copter. It was like an aerial food processor.
