I knew a guy in a Fletcher topdresser who had a hawk enter through the front windscreen.
After impact, the stunned and dying bird went into full attack mode. I reckon the pilot did an excellent job of not losing control at low level.
I overshot once from about 200' to avoid a hawk crossing final. We eyeballed each other. It wasn't giving way. I've taken evasive action on several occasions to avoid any birds I've seen, usually seagulls and similar. Never hit anything.
