The American Crow (Corvus brachyrhynchos) is a common and widespread bird. They travel mostly in small groups, but sometimes in large flocks. (And a group of crows is known as a "murder"!) They can be found in all open habitats: from beaches and farmlands to suburbs and open woods. At night, they form large communat roosts where thousands gather in trees. Crows construct their nests of twigs and sticks and line them with bark, grass, and moss and place them in trees. Their diet is varied- they are opportunists and eat insects, nuts, seeds, corn, fruit, bird eggs and nestlings and carrion. They are all black, including their legs and large bills. Their call is an easily recognized "caaw, caaw".
