Crows live everywhere in the world except Antarctica and are a part of myths and legends in many cultures. Their reputation in the stories varies from comical to frightening, godlike or wise, bringers of light and bringers of death, though a “murder” of crows refers to a flock of crows, and not to anything murderous, at all. They may be all these things, but what we are learning is that they are especially smart.
