I wasn't very high, but I probibally set a record for size. I had a darned buzzard hit the nose of my 310R at 900' over BKL just to the left of center on the nosecone. He ricochet off the nosecone and into the left propeller splattering his innards and outards all over the windscreen, empanage, and wing. Had to be as big as a goose, although I never saw him (nearly midnight)... come to think of it... it was a goose. (Cost my company nearly $6k)
