Crows are territorial about their nesting area and have feeding areas separate from the nesting area that they are also protective of. But they don't seem as strict about the feeding areas. I've sometimes seen raptors in the feeding area being ignored by the crows.

A funny-to-humans story about crows:
I was waiting in a drive thru lane when I realized I had heard angry crows for some time. I couldn't see them, then as the line turned the corner I caught glimpses of a very big bird. Hawk? That would explain the crows. A bit later I turn the second corner and the large bird is a full-grown American Bald Eagle doing lazy loops about 100 feet up. As I move forward I finally see the crows.
