Clark's nutcracker (Nucifraga columbiana), sometimes referred to as Clark's crow or woodpecker crow, is a passerine bird in the family Corvidae, native to the mountains of western North America. The nutcracker is an omnivore, but subsists mainly on pine nuts, burying seeds in the ground in the summer and then retrieving them in the winter by memory.
Nucifraga columbiana can reach an average length of 28.8 cm (11.3 in). It is slightly smaller than its Eurasian relative the spotted nutcracker (N. caryocatactes). Most of its body has feathers that are ashy-grey and loose in texture. The wings and tail are black and white. The central tail feathers are black and the outer ones white. The bill, legs and feet are also black. The bill is long, stout, and cone-shaped.
