The Steller's jay (Cyanocitta stelleri) is a jay native to western North America, closely related to the blue jay found in the rest of the continent, but with a black head and upper body. It is also known as the long-crested jay, mountain jay, and pine jay. It is the only crested jay west of the Rocky Mountains. The head is blackish-brown with light blue streaks on the forehead. This dark coloring gives way from the shoulders and lower breast to silvery blue. The primaries and tail are a rich blue with darker barring. It has been infrequently spotted in the COSA, but is a year-round resident throughout its range.
