The great horned owl is the most deadly enemy of the crow, taking old and young from their nests at night and killing many at their winter roosts.
Blue jays (Cyanocitta cristata) are a close second enemy, followed by all other small birds.
Great horned owls tend to attract clamors of noisy, excited mobs of crows. If an owl is discovered by a crow, the alarm is immediately given and all the crows within hearing respond to the call, gather about the owl flying around or perching in the tree as near to the owl as they dare go, cawing loudly and making a great fuss. They are seldom bold enough to strike the owl.
