I like the fact that they are so ... observant. A specific crow (I recognize him due to the missing feathers around his collar) will spend a while sitting on a tree outside my window, observing me for no reason. I do feed them generally by leaving peanuts in a specific area in the backyard early in the morning, and I'm sure this one partakes in the feast; but I have never rewarded his presence in any form, and yet there he is, in the middle of the day, just hanging out on the branch of the leafless tree, just sitting there, observing me. If I turn around and make eye contact, he often flies away. But I can see him in the reflection on my ipad's screen, and if I don't turn around and make eye contact, he will stay there for a while. It is fun interacting with "smart" creatures who have their own personalities and active social lives.
