I love crows so much. I had some in my backyard that I would give stuff too a lot. When I would leave in the morning for work, they would perch on my gutters and make clucking sounds while looking down at me. I'd wave and be on my way.
Now they are arriving slightly before the hawks and other predators and scaring them off.
If you see crows randomly arrive, and look around, there is almost always a circling bird in the sky.
It's super cool.
