Clark's nutcracker in the context of "Arc Dome Wilderness"

The northern nutcracker (Nucifraga caryocatactes), previously known as the spotted nutcracker and Eurasian nutcracker, is a passerine bird in the crow family Corvidae. It is slightly larger than the Eurasian jay but has a much larger bill and a slimmer looking head without any crest. The feathering over its body is predominantly chocolate brown with distinct white spots and patches. The wings and upper tail are black with a greenish-blue gloss.

The northern nutcracker is one of four species of nutcracker currently accepted. The southern nutcracker (Nucifraga hemispila) and the Kashmir nutcracker (Nucifraga multipunctata) were formerly considered as subspecies of the northern nutcracker. The species complex was known by the English name "spotted nutcracker". The fourth and most distinct member of the genus, Clark's nutcracker (Nucifraga columbiana), occurs in western North America.
