Some guys I worked with hit a fruit bat in a Huey at night, came in through the chin bubble and ended up in their lap.
Also an eagle in the helo training area at Canberra attacked one of our Squirrels one day, just dived right into the disc and forced them to land in a paddock. No airframe damage as I recall, but a truly stuffed eagle.
And once at Wagga I hit a galah with the skids of an AS350, just stunned him and broke a wing so I landed, hopped out and grabbed him in my hat.
Took him home and tamed him - top little fella until he realised he could fly again one day and headed off into the wild blue yonder!
