Northwestern Crows are thought to have evolved in coastal areas with Native American villages, thus adapted to living around people. Why the eastern crows didn't do the same, I don't know, except that crows have been agricultural pests in the East for a very long time and were often sighted at the end of a gun barrel. That may be why they aren't so tame.

Behaviorally, I have noticed the crows on the West coast are more "tame" than East coast birds. I would never see crows just walking around with the pedestrians on busy city streets out East. And I never was able to approach crows so closely until moving here.

This has been a long time in coming and is based on scientific data. Personally I feel there is a difference in vocalization with American Crows and the size difference can be quite obvious. Also habitat: "Northwestern" Crows are rarely found too far from shore. To me there also is a difference between calls of American Crows here in the Northwest and birds on the East Coast. I have never heard a crow in Maryland doing the "meow" call you can hear here frequently. Another interesting observation, is that I have never seen a roadkill-ed crow on the East Coast, but see many around here! Just thinking!
