Clark's Nutcracker, Nucifraga columbiana, is a large passerine bird, in the family Corvidae. It is slightly smaller than its Eurasian relative the Spotted Nutcracker (N. caryocatactes). It is ashy-grey all over except for the black-and-white wings and central tail feathers (the outer ones are white). The bill, legs and feet are also black.
