Western scrub-jays have long tails and small bills. The head, wings, and tail are blue, the back is brown, the underside is gray to tan, and the throat is white. Unlike the Steller’s jay and the blue jays, they do not have a crest. Western scrub jays include several subspecies that live along the Pacific coast and in the interior West. The Pacific coastal group has a distinct blue collar and is brighter in color than those of the interior West. They also have beaks that are short and hooked for eating acorns, while interior scrub jays have longer, more pointed beaks for extracting pine nuts from pinecones. Their behavior can be bold and inquisitive, and their calls can be loud and raucous, although the jays of the interior tend to be quieter, and their calls are lower-pitched than those of the coast. Western scrub jays are about 11.5 inches (29 centimeters) in length and have a wingspan of just over 15 inches (38 centimeters).
