Gymnorhinus cyanocephalus
The Pinyon Jay (Gymnorhinus cyanocephalus) is a strikingly social and highly specialized corvid, a denizen of western North America's arid pinyon-juniper woodlands. This medium-sized jay measures about 25-29 cm (10-11.5 in) in length, with a wingspan of 40-45 cm (16-18 in) and a weight ranging from 85-115 g (3-4 oz). Its plumage is a distinctive, uniform dull blue-violet, often appearing slightly darker on the head and lighter, almost grayish, on the underparts, with a short, somewhat stocky ...
Pinyon Jays are highly specialized for arid, semi-arid pinyon-juniper woodlands, but also utilize open pine-oak woodlands and sagebrush steppe with scattered pines, typically at elevations between 1,200 and 3,000 meters.
The Pinyon Jay's diet is overwhelmingly dominated by Pinyon pine seeds, supplemented by juniper berries, acorns, and a significant intake of insects (especially during the breeding season), which they forage for primarily on the ground or within trees.
These are intensely social, diurnal birds that forage and move in large, often raucous, flocks numbering from dozens to hundreds, communally roosting in dense trees. Their primary foraging strategy involves ground gleaning and probing for cached seeds, but they also expertly extract seeds directl...
The Pinyon Jay is endemic to western North America, primarily inhabiting the interior arid and semi-arid regions. Its core breeding and year-round range extends from central Oregon, southern Idaho, and Montana south through Wyoming, Colorado, Utah, Nevada, Arizona, New Mexico, and into western Te...

- The Pinyon Jay has an exceptionally long, pointed bill perfectly adapted for prying open the cones of pinyon pines to extract seeds. - An individual Pinyon Jay can cache tens of thousands of pinyon pine seeds over a single season, burying them shallowly across a wide area. - Studies show Pinyon...
