Any bird who lives primarily in the water is dumb as shit. They have unlimited protection above and around them, so they have zero adaptive pressure to put anything into their intelligence. Land birds have a lot to worry about so their brains adapted near-human levels of intellect.

A land bird flew into my window so hard I was worried it died this morning. This happens once a month to my knowledge and I don’t spend long in my bedroom outside sleeping. Land birds aren’t smart outside of a few select species lol

Put some stickers on your window

That just gives them a target. They can’t see the window. This is a real problem in some cities. AFAIK no one has found a real solution other than frosting the windows, but then humans can’t see through the windows and get irritated.
