Discussion Distinctive bird with a typical jaylike appearance: slim body, long tail, and stout, and rather elongated bill. Occurs as two subspecies groups in U.S.: Pacific birds (comprising three subspecies found on the Pacific coast) are more colorful than interior birds (three subspecies that occur inland). Some individuals, particularly Pacific birds, are bold, tame, and inquisitive, and easy to see; birds from interior south and east of range are more retiring and unobtrusive. An opportunistic feeder with an omnivorous diet that includes berries, fruits, insects, and the eggs and young of songbirds. Sexes are similar.
