Small birds often "mob" much larger hawks, owls, crows, and ravens.
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!
