The largest thing I’ve hit with a windshield was a hen pheasant - can’t imagine the thump from a big old buzzard.
Buzzards are pretty light and surprisingly fragile. Lotsa wingspan, but not very heavy.
I bet that pheasant was heavier.
Yep, they are set to run in economy mode, they can go for a week or more at a time between meals too.
