I had birds poop in my hair twice in one day.
She still wins.
I had a large vulture drop its “load” right on my windshield, as I was tooling down a busy Interstate, some years back. It looked like an instant curtain coming down. Talk about your vision impairment! The “splatter” covered almost my entire windshield. Best I could do was quickly hit my emergency flashers and gingerly pull off, hoping there was no obstruction on the shoulder. Then use about half the reservoir of wiper fluid.
Well, at least that wasn’t in my hair!
She had snake venom on her glasses, so the hawk probably saved her from getting snake bit.
