Clark's Nutcracker occurs in central to west coast N America from Canada to California. Nutcrackers have a special projection inside the lower mandible of their bill that makes it easier for them to crack nuts. Nutcrackers also have a throat pouch in which they can carry food items without having to swallow them. The young are fed from this. Nutcrackers have the same dipping flight as Jays and the same habit of burying nuts.
Nutcrackers normally bury nuts further up hill than they collect.
It has been shown that they can find buried nuts even after they are covered in snow. Breeding starts in March or April depending on latitude and in some places at least, breeding success is related to the hazel nut crop. The better the hazel nut crop the more eggs the female will lay. Clark's Nutcrackers are not so predictable in the placement of their nests. The female lays 3-5 eggs.
