The impression received from a casual notice of a specimen of the _Q. purpureus_ is that of a uniformly glossy black bird, the metallic tints being much broken or irregularly distributed, being frequently, or generally, arranged in successive bands on the feathers over the whole body, producing a peculiar iridescent effect. In the _Q. æneus_ nothing of this character is seen; for, among a very large series of western specimens, not one has the body other than continuous bronze, the head and neck alone being green or blue, and this sharply and abruptly defined against the very different tint of the other portions. These colors, of course, have their extremes of variation, but the change is only in the shade of the metallic tints, the precise pattern being strictly retained. In the present species the colors are more vivid and silky than in the eastern, and the bird is, in fact, a much handsomer one. (Ridgway.) Just after moulting, the plumage is unusually brilliant, the metallic tints being much more vivid. HABITS. The Bronzed Blackbird has been so recently separated from the _purpureus_ that we cannot give, with exactness or certainty, the area over which it is distributed. It is supposed to occupy the country west of the Alleghanies as far to the southwest as the Rio Grande and Fort Bridger, extending to the Missouri plains on the northwest, to the Saskatchewan in the north, and to Maine and Nova Scotia on the northeast. Subsequent explorations may somewhat modify this supposed area of distribution. It is at least known that this form occurs in Texas, in all the States immediately west of the Alleghanies, and in the New England States, as well as the vicinity of New York City. In regard to its habits, as differing from those of _purpureus_, we are without any observations sufficiently distinctive to be of value. It reaches Calais about the first of April, and is a common summer visitant. In the fall of 1869, about the 10th of October, several weeks after the _Quiscali_ which had been spending the summer with us had disappeared, an unusually large number of these birds, in the bronzed plumage, made their appearance in the place; they seemed to come all together, but kept in smaller companies. One of these flocks spent the day, which was lowering and unpleasant, but not rainy, in my orchard. They kept closely to the ground, and seemed to be busily engaged in searching for insects. They had a single call-note, not loud, and seemingly one of uneasiness and watchfulness against danger. Yet they were not shy, and permitted a close approach. They remained but a day, and all were gone the following morning. On the day after their departure, we found that quite a number of apples had been bitten into. We had no doubt as to the culprits, though no one saw them in the act.
