> 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.

I've seen gulls having fun like that. And they are quite cunning. There are videos from all around the UK coast of gulls shoplifting.
