With a hypothetical center of distribution somewhere in southeastern British Columbia, this subspecies inosculates with _stelleri_ in the mountains of that province, and is roughly separated from the western stock by the central ridge of the Cascades, in Washington. Black-headed Jays in Washington are normally confined to the limits of coniferous timber, being therefore most abundant in the northern portion, in the Blue Mountains, and along the eastern slopes of the Cascades. We have, however, like Bendire, discovered them on occasion skulking in the willows along creek bottoms some twenty miles from pine timber. On the other hand, they do not assert, with the Gray Jays and Clark Crows, the right to range the mountain heights: but are quite content to maintain their unholy inquisition amidst the groves and thickets of the valley floors. They are, perhaps, not so noisy as the Steller Jays, being less confident of their cover; and their notes are rather more musical (breath of pines is better than fog for the voice); but for the rest they are the same vivacious, intrepid, resourceful mischief-makers as their kin-folk everywhere. No. 12. WHITE-HEADED JAY. A. O. U. No. 484a. Perisoreus canadensis capitalis Ridgw. Synonyms.—Rocky Mountain Jay. “Canada” Jay. Whiskey Jack. Wisskachon. Camp Robber. Moose-bird. Meat Hawk. Meat-bird.

Bill and feet black; iris brown. _Young birds_ much darker and more uniform in coloration than adults—slaty gray to sooty slate with lighter crown and some whitish edging on underparts.

White of head with its abruptly defined patch of slate on hind neck distinctive as compared with related species of the genus _Perisoreus_. Nesting.—Has not been reported for Washington but bird undoubtedly breeds in the Kalispell range. _Nest_: in coniferous tree, a large compacted mass of the softest and warmest substances,—twigs for a foundation, then grasses, abundant moss, plant-down and feathers. _Eggs_: 3-5, usually 4, grayish white, spotted and blotched with brown having a tinge of purplish. Av. size 1.15 × .85 (29.2 × 21.6). _Season_: Feb.-April; one brood. General Range.—Higher ranges of the Rocky Mountain district from British Columbia to Arizona. Range in Washington.—Mountains of northeastern corner of State and (probably) the Blue Mountains.
