A young bird is soft, dull orange beneath, palest on the throat, and tinged along the sides with olive; above olive, with an orange cast on the rump and tail, the latter being without any black; centres of dorsal feathers blackish; wings blackish, with two broad white bands across coverts, and broad edges of white to the tertials. Specimens collected in Western Kansas, by Mr. J. A. Allen, have the middle wing-coverts pure white instead of deep orange, and, according to that naturalist, have more slender bills than Eastern birds. Mr. Allen thinks they form a race peculiar to the plains; but in examining the series of specimens in the museum of the Smithsonian Institution, we have failed to discover any constancy in this respect. A male (5,356, Farm Isl., May 30) from Nebraska has the middle wing-coverts pure white,—the lesser, clear orange; the black throat-stripe is almost separated from the black of the cheeks by the extension forward of the orange on each side of it, only the tips of the feathers being black. No. 61,192 ♂, Mount Carmel, Ill. (August 12), has the throat-stripe even more isolated, being connected anteriorly for only about a quarter of an inch with the black of the jaw; there is also a distinct indication of an orange superciliary stripe, mostly concealed, however, by the black tips of the feathers. The middle coverts, like the lesser, are pure plain orange. A male from Cape May, N. J. (59,458, May), has the middle coverts white, and the lesser wholly uniform black. The head, however, is as in typical specimens. In a series of twenty adult spring males from Carlisle, Penn., seven have the middle coverts more or less white. But it is noticed that all these specimens with white middle coverts have invariably less intense colors than those with orange shoulders, while in the Kansas specimens the other colors are of the brightest character. A male from Washington (12,317, May 6) is exactly similar. HABITS. The familiar Baltimore Oriole, the Golden Robin of the New England States, is found throughout eastern North America, at various seasons, from Texas to the British Possessions, and from the Atlantic to the plains. It is, however, for the most part, not common beyond the Mississippi River. It has been traced as far to the north as the 55th parallel of latitude, and probably breeds more or less abundantly in every State east of the Mississippi River. It is rare in Florida, and is not given by Mr. Allen as known to that State, but I have received its nest and eggs from Monticello in West Florida. The Smithsonian Museum embraces specimens from as far west as Powder River and the Yellowstone.
