SONG SPARROW

      ? Fringilla cinerea, Gmelin, I, 1788, 922 (based on Cinereous Finch, Lath. II, 274).—Penn. Arc. Zoöl. II, 68 (Unalaschka). Emberiza cinerea, Bonap. Consp. 1850, 478. Melospiza insignis, Baird, Trans. Chicago Acad. I, ii, 1869, p. 319, pl. xxix, fig. 2.—Dall & Bannister, do. p. 285.—Finsch, Abh. Nat. III, 1872, 44 (Kodiak).

      Sp. Char. Summer plumage (52,477 ♂, Kodiak, May 24, 1868). Above brownish-plumbeous, outer surface of wings somewhat more brown, the greater coverts slightly rufescent. Interscapulars with medial broad but obsolete streaks of sepia-brown; crown and upper tail-coverts with more sharply defined and narrower dusky shaft-streaks. Crown without medial light line. Beneath grayish-white, much obscured by brownish-plumbeous laterally. A whitish supraloral space, but no appreciable superciliary stripe; a whitish maxillary stripe; beneath it an irregular one of dusky sepia; irregular streaks of dark grizzly-sepia on breast and along sides, blended into a broad crescent across the jugulum. Wing, 3.30; tail, 3.50; bill, .48 from nostril, .28 deep at base, and .21 in the middle, the middle of the culmen being much depressed, its extremity rather abruptly decurved.

      Autumnal plumage (60,162, Kodiak, received from Dr. J. F. Brandt). Differs very remarkably in appearance from the preceding. The pattern of coloration is everywhere plainly plotted, there being a distinct vertical and sharply defined superciliary stripe. Ground-color above ashy, somewhat overlaid by rusty, except on the sides of the neck. Whole crown, outer surface of wings, and dorsal streaks, rusty rufous; black streaks on crown and upper tail-coverts obsolete. Beneath pure white medially, the markings rusty rufous. Wing, 3.30; tail, 3.60; bill, .47 and .30.

      Hab. Kodiak and Unalaschka.

      This race represents the extreme extent of variation in the species, and it would be difficult for a species to proceed farther from the normal standard; indeed, the present bird is so different even in form, especially of bill, from melodia, that, were it not for the perfect series connecting them, few naturalists would hesitate to place them in different genera.

      Habits. No information has so far been published in reference to the nesting of this Sparrow, or of any peculiar habits.

Melospiza lincolni, BairdLINCOLN’S FINCH

      Sp. Char. General aspect above that of M. melodia, but paler and less reddish. Crown dull chestnut, with a median and lateral or superciliary ash-colored stripe; each feather above streaked centrally with black. Back with narrow streaks of black. Beneath white, with a maxillary stripe curving round behind the ear-coverts; a well-defined band across the breast, extending down the sides, and the under tail-coverts, of brownish-yellow. The maxillary stripe margined above and below with lines of black spots and a dusky line behind eye. The throat, upper part of breast, and sides of the body, with streaks of black, smallest in the middle of the former. The pectoral bands are sometimes paler. Bill above dusky; base of lower jaw and legs yellowish. Length, 5.60; wing, 2.60.

      Hab. United States from Atlantic to Pacific, north to the Yukon River and the Mackenzie, and south through Mexico to Panama. Oaxaca (Scl. 1858, 303); Xalapa (Scl. 1859, 365); Guatemala (Scl. Ibis, I, 18); Vera Cruz, winter (Sum. M. B. S. I, 552).

      There is little or no difference in specimens of this bird from the whole of its range, except that one from near Aspinwall is considerably smaller than usual, the streaks on the back narrower, and the color above more reddish. A young bird from Fort Simpson, on the Mackenzie, is much like the adult.

      Habits. Lincoln’s Finch was first met with by Mr. Audubon in Labrador, and named in honor of one of his companions, Mr. Thomas Lincoln, now residing at Dennysville, Maine, by whom the first specimen was procured. His attention was attracted to it by the sweet notes of its song, which, he states, surpass in vigor those of any of our American Sparrows with which he was acquainted. He describes this song as a compound of the notes of a Canary and a Woodlark of Europe. The bird was unusually wild, and was procured with great difficulty. Other specimens, afterwards obtained, did not exhibit the same degree of wildness, and they became more common as the party proceeded farther north. He did not meet with its nest.

      He describes the habits of this species as resembling, in some respects, those of the Song Sparrow. It mounts, like that bird, on the topmost twig of some tall shrub to chant for whole hours at a time, or dives into the thickets and hops from branch to branch until it reaches the ground in search of those insects or berries on which it feeds. It moves swiftly away when it discovers an enemy, and, if forced to take to flight, flies low and rapidly to a considerable distance, jerking its tail as it proceeds, and throwing itself into the thickest bush it meets. Mr. Audubon found it mostly near streams, and always in the small valleys guarded from the prevalent cold winds of that country.

      He also describes this species as eminently petulant and pugnacious. Two males would often pursue each other until the weaker was forced to abandon the valley, and seek refuge elsewhere. He seldom saw more than two or three pairs in a tract of several miles in extent. By the 4th of July the young had left their nests and were following their parents. As from that time the old birds ceased to sing, he inferred that they raised but one brood in a season. Before he left Labrador these birds had all disappeared.

      Although first discovered on the coast of Labrador, subsequent explorations have shown this bird to be far more common at the West than it is at the East, where indeed it is exceedingly rare. Not a specimen, that I am aware of, has ever been found in Maine, although it probably does occasionally occur there; and only a very few isolated individuals had been taken in Massachusetts before the spring of 1872, when they were noticed by Mr. Brewster and Mr. Henshaw in considerable numbers. These birds, seven or eight in number, were shot, with two exceptions, in May, between the 14th and the 25th. Three were taken in Springfield by Mr. Allen, one in Newburyport by Mr. Hoxie, two in Hudson by Mr. Jillson, and two in Cambridge by Mr. Brewster. The latter were obtained, one in September and the other in October. In May, 1872, Mr. Brewster obtained six others. Mr. Allen had met with this Finch in Wayne County, N. Y., in May, where it was not uncommon, and in Northern Illinois, where it was quite numerous. A few have been taken near New York City, and in the neighborhood of Philadelphia, where they are regarded as very rare. Professor Baird, however, frequently met with them at Carlisle, Penn.

      Farther west, from the Mississippi Valley to the Pacific, they are much more common. Mr. Ridgway states that they occasionally winter in Southern Illinois, where they frequent retired thickets near open fields. They have been found breeding near Racine, Wis., by Dr. Hoy, and have been met with also in Nebraska in considerable numbers; and, during the breeding-season, Mr. Audubon met with them on the Upper Missouri.

      From March to May Mr. Dresser found these birds very abundant in the fields near the San Antonio River, and in some swampy grounds. They seemed to prefer that sort of locality, and the banks of the river, keeping among the flags and rushes. Their stomachs were found to contain small seeds. Mr. Lincecum also met with a few in Washington County of the same State.

      It was not met with in Arizona by Dr. Coues, but Dr. Kennerly found it in the month of February from the Big Sandy to the Great Colorado River. It confined itself to the thick bushes along the streams, and when seen was generally busily hopping from twig to twig in search of food. When started up, its flight was very rapid and near the earth.

      Dr. Heermann obtained this species, not unfrequently, both in Northern California and in the Tejon Valley. On all occasions he found it in company with flocks of Sparrows, composed of several species.

      Lieutenant Couch took this species at Tamaulipas, Mexico, and at Brownsville, Southwestern Texas, in March. It has also been seen in May, at the Forks of the Saskatchewan, by Captain Blakiston.
