Some birds mind their own business. Crows do not.
They keep an eye on you. They study you. I guess this can be rewarding for them, since they are scavengers and we are messy and careless.
This crow flew over to perch near me as I walked up the path onto the berm at the entrance to Green River. It flew a short distance and I followed, then I walked off and it followed me.
I assume it was a Fish Crow because of my location. I had come with my camera for Kites – Swallow-tailed or Snail. Didn’t find them.
Calling now and then, maybe to let another crow nearby know something about the situation? “Betty, I’m watching a human. Keep the kids quiet. I’ll see if she squashes a lizard or drops a cracker.”
Do crows caw at people? I doubt it. But if so, they are talking and we just aren’t getting it.
I’ve noticed that when Blue Jays are watching you and you start watching them back, they don’t like it and they fly off. But crows will hold your gaze longer. They are interested; we are interesting.
Some people are birdwatchers, but all crows are peoplewatchers.
