In all the fertile portions of the country west of the plains, Mr. Ridgway found Bullock’s Oriole—the western representative of the Baltimore—extremely abundant. In May, when the valley of the Truckee, near Pyramid Lake, was visited, he observed great numbers feeding upon the buds of the grease-wood, in company with the Louisiana Tanager and the Black-headed Grosbeaks. In certain localities there was scarcely a tree that did not contain one or more nests of these birds, and as many as five have been found in a single tree. Although constructed in a manner almost precisely similar to those of the common eastern species, its nest is less frequently pendulous, being in many cases fixed between the upright twigs near the top of the tree. It is, however, not unfrequently suspended, like that of the Baltimore, from the extremity of a drooping branch, though very rarely in so beautiful a manner. The notes of this Oriole, which are similar to those of the Baltimore, are neither so distinct, so mellow, nor so strong, and their effect is quite different from that produced by the splendid mellow whistling of the eastern species; and the mellow, rolling chatter so characteristic of the latter is not so full in the western species, and generally ends in a sharp _chow_, much like the curious mewing of an _Icteria_. He regards Bullock’s Oriole as altogether a less attractive species. Mr. Lord found this bird by no means an abundant species in British Columbia. Those that were seen seemed to prefer the localities where the scrub-oaks grew, to the pine regions. He found their long, pendulous nests suspended from points of oak branches, without any attempt at concealment. He never met with any of these birds north of Fraser’s River, and very rarely east of the Cascades. A few stragglers visited his quarters at Colville, arriving late in May and leaving early in September, the males usually preceding the females three or four days. On the Shasta Plains Mr. Lord noticed, in the nesting of this bird, a singular instance of the readiness with which birds alter their habits under difficulties. A solitary oak stood by a little patch of water, both removed by many miles from other objects of the kind. Every available branch and spray of this tree had one of the woven nests of this brilliant bird hanging from it, though hardly known to colonize elsewhere in this manner.
