HABITS. The Rusty Blackbird is an eastern species, found from the Atlantic to the Missouri River, and from Louisiana and Florida to the Arctic regions. In a large portion of the United States it is only known as a migratory species, passing rapidly through in early spring, and hardly making a longer stay in the fall. Richardson states that the summer range of this bird extends to the 68th parallel, or as far as the woods extend. It arrives at the Saskatchewan in the end of April, and at Great Bear Lake, latitude 65°, by the 3d of May. They come in pairs, and for a time frequent the sandy beaches of secluded lakes, feeding on coleopterous insects. Later in the season they are said to make depredations upon the grain-fields. They pass through Massachusetts from the 8th of March to the first of April, in irregular companies, none of which make any stay, but move hurriedly on. They begin to return early in October, and are found irregularly throughout that month. They are unsuspicious and easily approached, and frequent the streams and edges of ponds during their stay. Mr. Boardman states that these birds are common near Calais, Me., arriving there in March, some remaining to breed. In Western Massachusetts, according to Mr. Allen, they are rather rare, being seen only occasionally in spring and fall as stragglers, or in small flocks. Mr. Allen gives as their arrival the last of September, and has seen them as late as November 24. They also were abundant in Nova Scotia. Dr. Coues states that in South Carolina they winter from November until March. These birds are said to sing during pairing-time, and become nearly silent while rearing their young, but in the fall resume their song. Nuttall has heard them sing until the approach of winter. He thinks their notes are quite agreeable and musical, and much more melodious than those of the other species. During their stay in the vicinity of Boston, they assemble in large numbers, to roost in the reed marshes on the edges of ponds, and especially in those of Fresh Pond, Cambridge. They feed during the day chiefly on grasshoppers and berries, and rarely molest the grain. According to Wilson, they reach Pennsylvania early in October, and at this period make Indian corn their principal food. They leave about the middle of November. In South Carolina he found them numerous around the rice plantations, feeding about the hog-pens and wherever they could procure corn. They are easily domesticated, becoming very familiar in a few days, and readily reconciled to confinement. In the District of Columbia, Dr. Coues found the Rusty Grakle an abundant and strictly gregarious winter resident, arriving there the third week in October and remaining until April, and found chiefly in swampy localities, but occasionally also in ploughed fields.
