Range. - Pacific coast from southern California to Alaska; resident and breeding throughout its range.
All the members of this sub-species are similar in plumage, having a sooty black head, crest and neck, shading insensibly into dark bluish on the back and underparts, and brighter blue on the wings and tail. They usually have a few streaks or spots of pale blue on the forehead. They are just as noisy, bold and thievish as the eastern Jay and are also excellent mimmics like the latter. They nest in fir'trees at any height from the ground and in April or May deposit their three to six greenish blue eggs which are spotted with various shades of brown. Size 1.25 x .90. Their nests are more bulky than those of the eastern Jay and are usually made of larger sticks and held together with some mud.
