Mr. J. A. Allen (Am. Naturalist, June, 1872) mentions finding this species at the base of the Rocky Mountains, in Colorado, which he regards as its extreme western limit. In Kansas he found this species, as well as the Orchard Oriole, abundant, the Baltimore indulging in a dialect so different from that of its northern relatives as often to puzzle him to make out to what bird its strange notes belonged. Its colors were also unusually bright in all the specimens he examined. Mr. Boardman gives it as very rare at Calais, but Professor Verrill thinks it common in Western Maine. It is abundant throughout the southern and central portions of Vermont, and New Hampshire, and in all New York. It is a common summer resident at Hamilton, Ontario, where it arrives the second week in May. It was found on the plains of the Saskatchewan by Captain Blakiston. Mr. Dresser states it to have been abundant at Matamoras, where it was breeding, though he was too late for its eggs. He saw none at San Antonio, but Mr. J. H. Clark was more fortunate. Numbers of them, he states, were seen nesting in the mesquite-trees on the prairies, at which time they were very musical, having sometimes as many as three nests in the same tree. These were all built of fine grass, among the top branches, and interwoven with the leaves. Dr. Woodhouse found it quite common in the Indian Territory and in Eastern Texas. Specimens of this species were taken by Mr. James M. Leannan, at Panama, which is presumed to be the most southern locality on record for this bird. The Baltimore Oriole is one of the most common birds nearly throughout New England. Gay and brilliant in plumage, interesting and lively in manners and habits, and a vocalist of rare power, with pathos, beauty, and variety in his notes, this bird has been, and would still be, a great favorite, but for its transgressions among the pea-vines of our gardens. He makes his appearance with exemplary punctuality, seeming regardless of the prematureness or tardiness of the season. Rarely does the 10th of May pass without the sound of his welcome notes, and rarely, if ever, does he come sooner. Their period of song is not a long one, but soon terminates, as family cares increase and the tender broods require an undivided attention. Early in July this Oriole ceases to favor the world with those remarkable notes that seldom fail to attract attention by their peculiarity, and to excite admiration by their rich and full-toned melody.
