Evidently they recognize their (perceived) enemies. For that matter crows often mob hawks and owls, too. What's ironic is that the smaller birds mob large, slow-moving buteos which don't normally prey on birds at all. I've never seen birds mob an accipiter or falcon, which would prey on small birds. (I once saw a single Goshawk attack 6 or 7 ravens; I'm not sure what to do with that data point.) Anyway, next time you're walking in the woods and come upon a flock of small birds making a lot of noise up in the trees be sure to stop and take a close look. The center of attention may be an owl or hawk! Wink Gross Tektronix, Inc.
