Gray Jays are found primarily in mature, humid, sub-alpine, spruce forests. The western scrub jay's plumage and behavior differ greatly between interior and coastal populations. Increased handling, searching, or recognition times for a preferred food item lowers its profitability. Despite their showy pink plumage and dazzling turquoise feathers on the wing-bend, jays are usually secretive birds that are difficult to spot for much of the year. These birds live year-round on permanent territories, surviving in cold winter months on food cached throughout their territory in warmer periods. – He can play the guitar and piano.

The key habitat requirements may be sufficiently cold temperatures to ensure successful storage of perishable food and tree bark with sufficiently pliable scales arranged in a shingle-like configuration that allows Canada jays to wedge food items easily up into dry, concealed storage locations. A single Gray jay may hide thousands of pieces of food per year and later find them, sometimes months after hiding them.

Males choose a nest site in a mature conifer tree and take a lead role in construction. [37] Canada jays have been seen landing on moose (Alces alces) to remove and eat engorged winter ticks (Dermacentor albipictus) during April and May in Algonquin Provincial Park. Monogamous, pairs remain together for life, though a bird will pair up with a new partner if it is widowed.
