Description: American Crows are black from beak to toe.
Adults have a light violet-blue gloss on the body and
a greenish-blue gloss on the wings. The eyes are dark
brown. Nasal bristles cover the basal third of the upper
mandible. Sexes are similar. Juveniles have duller plumage
than adults. Their blue-gray eyes turn brown as they
mature.

During fall and winter, American Crows may form communal
roosts with tens, hundreds, and even thousands of birds.
They will fly as far as 50 miles to forage, returning
along established flight routes to the roost each evening.
