I think they do that on purpose, that’s why they all sit so close on the powerline later, sharing a laugh about what each has been doing. ;^)
You’re probably right.
Whatever you do, don’t every piss off a crow. They have an uncanny ability to communicate with one another. A few years ago, there was a murder of crows perched in the trees in my backyard, and their cawing was driving me crazy. I finally took out my BB gun and took aim. I don’t think I hit one, but my windshield was covered in messy birdcrap the next day.
You piss off a crow, you piss off them all. Not recommended.
