_C. stelleri_, like _C. cristata_ again, is something of a mimic. The notes of the Western Red-tail (_Buteo borealis calurus_) and other hawks are reproduced with especial fidelity. For such an effort the Jay conceals himself in the depths of a large-leafed maple or in a fir thicket, and his sole object appears to be that of terrorizing the neighboring song-birds. One such I heard holding forth from a shade tree on the Asylum grounds at Steilacoom. Uncanny sounds are, of course, not unknown here, but an exploratory pebble served to unmask the cheat, and drove forth a very much chastened Blue Jay before a company of applauding Juncoes. It is well known that the gentleman burglar takes a conscientious pride in the safety and welfare of his own home. Nothing shall molest _his_ dear ones. The Jay becomes secretive and silent as the time for nest-building approaches. The nest is well concealed in a dense thicket of fir saplings, or else set at various heights in the larger fir trees. If one but looks at it before the complement of eggs is laid the locality is deserted forthwith. If, however, the enterprise is irretrievably launched, the birds take care not to be seen in the vicinity of their nest until they are certain of its discovery, in which case they call heaven and earth to witness that the man is a monster of iniquity, and that he is plotting against the innocent. In our experience, Steller’s Jay is not, as has been sometimes reported, a bird of the mountains. To be sure, it may be found in the mountain _valleys_, but if so it is practically confined to them. The bird, is, however, ubiquitous thruout the lowlying countries of Puget Sound, Gray’s Harbor, and adjacent regions, giving way only upon the south to the dubious Grinnell Jay (_S. s. carbonacea_). No. 10. GRINNELL’S JAY. A. O. U. No. 478e. Cyanocitta stelleri carbonacea J. Grinnell. Synonyms.—“Blue Jay.” Coast Jay (A. O. U.). Description.—“Similar to _C. s. stelleri_, but paler thruout, and averaging slightly smaller; color of head very nearly as in _C. s. stelleri_, but averaging browner or more sooty, the forehead always conspicuously streaked with blue, and throat more extensively or uniformly pale grayish; back and foreneck much paler, slaty brown or brownish slate, instead of deep sooty; blue of rump, upper tail-coverts, and under parts of body light dull cerulean or verditer blue, advancing more over chest, where more abruptly defined against the sooty or brownish slate color of foreneck.” (Ridgway). Adult males: wing 6.10 (150.5); tail 5.51 (140); bill 1.15 (29.1); tarsus 1.75 (44.5). General Range.—Pacific Coast district from Monterey county, California, north to Columbia River. Range in Washington.—Has only theoretical status in State, but specimens taken along north banks of Columbia would appear to belong here.
