The Canada jay (Perisoreus canadensis) – the national bird of Canada – was previously known as the grey (gray) jay. The name was changed in 2018 by the American Ornithological Society. It has pale grey underparts, darker grey upperparts, and a grey-white head with a darker grey nape. Tough enough to survive year-round in very cold climates, it stores excess food in bark crevices all summer, retrieving it in harsh weather. It is found in boreal forests of North America north to the tree line, and in the Rocky Mountains subalpine zone south to New Mexico and Arizona.
