Crows are very popular in literature and myth. In Roman mythology, crows, or ravens, were once as white as snow. In Norse mythology, the raven belonged to Odin, the god of war. The raven soared over the battlefield and fed on the bodies of the dead. The raven himself is hoarse That croaks the fatal entrance of Duncan Under my battlements.
Crows are very intelligent.
They have been taught to count, to recognize and match written figures and shapes, and to speak a few human words. Crows are very capable birds. They have many different types of cawing, which is how they communicate with one another. For example, they often feed in flocks, with one or two crows posted as lookouts. This enables the whole flock to escape unharmed.
