They "commute to work" each day. Crows all live in a community that they go home to each night, and then each morning they all come back to their specific areas, usually in pairs. If you're in a place where you see crows every day, it's almost certainly the same pair of crows you’re seeing each day.
Each pair has a strict territory. I don't know how it works in rural areas, but in my neighborhood the territories are demarcated by streets and cover one or two neighborhood blocks.
They definitely recognize me and follow me for the peanuts. Usually they'll follow me from one block to the next, and another pair will come up and chase them off.
They do seem to set aside their territorial fighting when there's a lot of food; a guy up the street from me throws ridiculous amounts of food onto his front lawn, like whole loaves of bread, to feed the birds (probably rats and coyotes too), and the crows all gather peacefully there every morning before heading back to their territories.
I would love to know how they determine who gets what territory. I assume it's handed down; every year there's a month or so when the adolescents come out (they're a little bit ganglier and pester their parents for food all the time rather than foraging for it themselves) so I think they're there to learn the ropes. Are there crow dynasties that have owned certain city blocks for generations? How long do they last?
Lots of interesting stuff to watch in the lives of crows.
