Nutcrackers are Jay-sized members of the crow family. Their plumage is mainly brown with white spots. Their white vents and tail tips are particularly prominent in flight. Their caps are a more even, darker brown and they have blackish wings. It can be hard to distinguish birds of the nominate race from the Siberia race; though the Siberian birds have slightly longer and narrower beaks, and a broader white band on their tail tip. Nutcrackers’ legs and beaks are black, and they have brown irises.
