Flocks
of crows range widely for food, up to 30 miles
a day in winter. Foods include grasshoppers,
caterpillars, grubs, worms, most insects,
grain, fruit, the eggs and young of other
birds, organic garbage -- just about anything
that they can find or overpower. Crows also
feed on the carcasses of winter- and road-killed
animals.
Crows
have extremely keen senses of sight and hearing.
They are wary and usually post sentries while
they feed. Sentry birds watch for danger,
ready to alert the feeding birds with a sharp
alarm caw. Once aloft, crows fly at 25-30
mph; with a strong tail wind, they can hit
60. These skillful fliers have a large repertoire
of moves designed to throw off airborne predators.
