Gymnorhinus Cyanocephalus – Pinyon Jay

Gymnorhinus Cyanocephalus - Pinyon Jay found in western part of the United States

The pinyon jay, Gymnorhinus cyanocephalus is a medium-sized jay that is similar in size to the North American blue jay and the Eurasian jay. The voice is described as a two- or three-times repeated rhythmic krawk-kraw-krawk. Gymnorhinus is the genus’s sole representative. Its overall dimensions are quite similar to those of a nutcracker, and this can be interpreted as convergent evolution, given both birds occupy comparable ecological niches.

Pinyon jays also consume bristlecone pine (Pinus aristata) seeds, limber pine (Pinus flexilis) seeds, and juniper berries. When insects, soft vegetation, and pinyon seeds are abundant, nestlings devour them.

Habitat

Pinyon jays inhabit arid mountain slopes and foothills adjacent to pinyon-juniper forests. It is also found in communities of sagebrush, scrub oak, and chaparral, as well as pine woods.

Behavior

Pinyon jays form huge groups, sometimes exceeding 250 to 500 individuals since they keep an eye out for predators while their partners eat seeds. They spend the majority of their time seeking seeds to consume immediately, conceal in the ground, or store in a tree fissure for later use. They seek protection among pinyon, western juniper, and ponderosa pine trees. Rarely do roosting locations occur in the region that was last utilized for foraging that day. A flock of pinyon jays in northern Arizona traveled 1 to 3 miles from the feeding spot before roosting. Roosting birds congregated in groups of three to five individuals.
