I miscalculated the distance, and I slammed into the window, headfirst.
Are you a pigeon
Do pigeons do that?
Loudly and hilariously, yes
A while back, a large woodpecker(a fantastically stupid bird, I’ve noticed) hit my glass balcony door so hard it dazed itself, and sat on its ass, wings lax to its sides, visibly reeling like in a cartoon. It then recovered, and promptly flew into the black metal railing of my balcony before finally escaping through the bars into the wooded area beyond.
And yeah, had a lot of mourning doves hit the door, too.
