Bird of sunshine and good cheer, springtime’s ripest offering and emblem of summer achieved, is this happy-hearted creature who flits about the orchards and timber cultures of eastern Washington. The willows of the brook, the cottonwoods and the quaking asps, were his necessary home until the hand of the pioneer made ready the locust, the maple and the Lombardy poplars, which are now his favorite abiding places. And so, for many years, the droning of bees, the heavy-scented breath of the acacia, and the high, clear whistling of the Oriole have been associated memories. [Illustration: BULLOCK’S ORIOLE.] A little less dandified than his eastern cousin, the lordly Bird of Baltimore, the Bullock Oriole fulfills much the same economy in habit, song, and nesting as that well-known bird. He is, if anything, a little less musical, also, and not so conspicuous. The males arrive a week or two in advance of their mates, and appear quite ill at ease until joined by their shy companions. Marriage compacts have to be settled at the beginning of the season, but rivalry is chiefly between the under-colored young blades who must make their peace with the sweet girl graduates of the previous year. Orioles are very closely attached to a suitable locality, once chosen, and a group of nests in a single tree presenting successive annual stages of preservation, is fairly eloquent of conjugal fidelity. [Illustration: _Taken near Spokane._ _Photo by F. S. Merrill._ FEMALE BULLOCK ORIOLE.] The purse-shaped nest of the Bullock Oriole is a marvel of industry and skill, fully equal in these respects to that of the Baltimore Bird. A specimen before me, from a small willow on Crab Creek, in Lincoln County, taken just after its completion, is composed entirely of vegetable fibers, the frayed inner bark of dead willows being chiefly in evidence, while plant-downs of willow, poplar, and clematis are felted into the interstices of the lower portion. This pouch is lashed at the brim by a hundred tiny cables to the sustaining twigs, and hangs to a depth of six inches, with a mean diameter of nearly three, yet so delicate are the materials and so fine the workmanship, that the whole structure weighs less than half an ounce. A more bulky, loose-meshed affair, taken at Brook Lake No. 4, in Douglas County, has a maximum depth of nine inches outside, a mean depth of six and a half inches inside, and a greater diameter of five inches.
