Description of the Clark's Nutcracker
The Clark’s Nutcracker is larger than most jays but smaller than crows, and is related to both. It is pale gray with black wings, a short black and white tail, and a white face.
Seasonal change in appearance
Similar to adults.
High elevation coniferous forests.
Pine seeds are an important component of the diet, but Clark’s Nutcrackers also eat nuts, berries, and insects, along with eggs and young of other birds.
The Clark’s Nutcracker forages both in trees and on the ground, and frequently stores seeds for later retrieval.
Clark’s Nutcrackers are found in mountainous habitat of the western U.S. Their population has increased in recent decades.

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.

Clark’s Nutcrackers may store tens of thousands of seeds annually, and they have a large capacity for remembering and retrieving these stored seeds over the winter.
Despite being found near the treeline in remote mountains, Clark’s Nutcrackers are often quite tame when it comes to accepting food from humans near campgrounds or trailheads.
During years when food is scarce, Clark’s Nutcrackers sometimes move to lower elevations far from their normal range.
Calls include a variety of loud, jay-like rattles or yelps
