They also like to annoy other animals. I have seen it now a few times that a crow or a group of crows would approach a dog from behind and nip their tail or butt. When the dog turns around the crow will jump back a little and pretend it has nothing to do with this. When the dog looks away they will do it again. I have seen similar behavior with swans. When my dog chases they get out of the way but only the minimum needed.

Very smart but obnoxious in a way.
