> Corvids and parrots and raptors are remarkably smart, yet not every bird species is. Some are incredibly stupid.

Raptors are pretty stupid. They don't _need_ to be smart. They're solitary and they are typically apex predators.

I have a great view out of my window, and I have a family of crows living nearby. They cooperated to drive out owls and eagles that were nesting in a nearby park. Right now it's raining with pretty strong gusty winds and the crows are flying outside, doing pretty crazy aerobatics. They are clearly having a lot of fun!

I have never seen pigeons or seagulls do that.
