Clark's nutcracker (Nucifraga columbiana)

Clark's nutcracker, sometimes referred to as Clark's crow or woodpecker crow, is a passerine bird in the family Corvidae. It is slightly smaller than its Eurasian relative the spotted nutcracker. It is ashy-grey all over except for the black-and-white wings and central tail feathers. The bill, legs and feet are also black. This bird derives its name from the explorer William Clark.
