This crow does not migrate. Scientists are not sure if the Northwestern Crow is a subspecies of a larger relative, the American or Common Crow Corvus brachyrhynchos who is found in most other areas of North America. Other than size, they can be told apart by where they live, their calls and the speed of their wing beat. Other calls sound similar. Northwestern crows, being smaller, also have a slightly faster wing beat in flight.
Crows are among the most intelligent of birds.
They hide food on the beach and use landmarks to find it again. If those landmarks are moved, the crow is unable to find the food. Crows are great mimics and can learn a great variety of sounds including talking. The Raven and Crow both belong to the Family Corvidae and are easily told apart in flight. The Raven is about twice as big as the crow with a heavier beak and more pronounced fan or flare to the tail.
