The grey jay, Perisoreus canadensis, is one of three species making up the Perisoreus genus, the smallest of the 10 genera containing jays. A non-migranting bird, the grey jay is found throughout the coniferous forests of North America and into the subalpine regions of Northern Arizona and New Mexico. Breeding pairs are monogamous and accompanied by one, sometimes two, stay-overs from the previous season to assist in protecting the nest and feeding the chicks after they hatch. The male determines a suitable nesting site and shows a strong preference for mature black spruce. The nest is built close to the trunk and facing a southwestern direction. Eggs are laid from March to April and a typical clutch can number from 2 to 5 eggs. The female will remain in the nest throughout the incubation period; for about 18 days she will rely on her mate to bring food.
