    What does the American Crow look like?
    Male and female American Crows look alike, with all-black plumage that has an iridescent purple sheen in direct light. Corvus, the first part of the American Crow's scientific name, simply means “crow,” and its species name brachyrhynchos means "short beak" — which is true only in comparison to its larger, similar-looking relative the Common Raven.
