Kind of off topic but I just got back from the park and there is a public water bowl set out for dogs and a crow was manipulating something in the water - after a time my eyebrows went up as I realized the crow was softening some dried out discarded human food to make it easy to break up and eat!

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.

We have been very welcoming to the crows in our backyard and they now hang out with the chickens and ducks when they get leftovers / table scrapes.

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.
