At the risk of exposing my identity to plenty of people:
Hit a hawk with a 76 a few days ago, sparrow(?) yesterday. Saw the hawk in time to pull up and was able to alter the impact to the nose, about 6 inches ahead of the windshield. Bird goo from point of impact to the rotor head. Took a long time to wash off. Impact at approx 145 KIAS, 800'. Impact was very loud and broke the left wiper.
The little one was just like a big bug. No time to see it, just a bloody mess in the center of the copilot's windshield. He didn't notice until he looked up.
All others were too long ago to recall the details (longer than this tour :-).
