СКАЧАТЬ species is stated to be a constant resident in the district wherein it is found, never ranging far from the thicket which contains its nest, or the house in the neighborhood of which it finds food and protection. Almost every winter morning, as well as during the summer, as Dr. Cooper states, its cheerful song may be heard from the garden or the fence, as if to repay those whose presence has protected it from its rapacious enemies. When unmolested, it becomes very familiar, and the old birds bring their young to the door to feed, as soon as they can leave their nest. Their song is said to so closely resemble that of the eastern bird, in melody and variety, that it is impossible either to tell which is the superior or to point out the differences. In wild districts it is always to be found near the sides of brooks, in thickets, from which it jealously drives off other birds, whether of its own or other species, as if it considered itself the proprietor. Its nest is built on the ground or in a low bush. Dr. Cooper has seen newly fledged young as early as May 6, at Olympia, though the rainy season was then hardly over.

      Mr. Nuttall pronounces its song as sweeter and more varied in tone than that of the Song Sparrow. He heard their cheerful notes throughout the summer, and every fine day in winter until the month of November, particularly in the morning, their song was still continued. Their nests and eggs were not distinguishable from those of F. melodia. The nests were composed of dry grasses, lined with finer materials of the same, and occasionally with deer’s hair. He states that they keep much in low ground and alluvial situations, amidst rank weeds, willows, and brambles, where they are frequently to be seen hopping about and searching after insects, in the manner of the Swamp Sparrow, which they so much resemble in their plumage. They are usually very solicitous for the safety of their young or for their nests and eggs, keeping up an incessant chirp. They raise several broods in a season, and are, like the Song Sparrow, also engaged nearly the whole of the summer in the cares of rearing their young.

      Mr. Townsend met with this species through several hundred miles of the Platte country in great numbers, as well as on the banks of the Columbia, generally frequenting the low bushes of wormwood (Artemisia). It appeared also to be a very pugnacious species. Two of the males were often observed fighting in the air, the beaten party going off crestfallen, and the conqueror repairing to the nearest bush to celebrate his triumph by his lively and triumphant strains. He again met with these birds, though not in abundance, in June, 1825, at the mouth of the Lewis River, on the waters of the Columbia.

      This Sparrow was also found very numerous at Sitka, by Mr. Bischoff, but no mention is made of its habits.

Melospiza melodia, var. rufina, BairdRUSTY SONG SPARROW

      Emberiza rufina, “Brandt, Desc. Av. Rossic. 1836, tab. ii, 5 (Sitka),” Bonaparte. Passerella rufina, Bonap. Consp. 1850, 477. (This may refer to Passerella townsendi, but is more probably the present bird.) Melospiza cinerea, Finsch, Abh. Nat. III, 1872, 41 (Sitka). (Not Fringilla c. Gmel.) M. guttata, Finsch, Abh. Nat. III, 1872, 41 (Sitka). (Not Fringilla g. Nutt.)

      Sp. Char. Resembling M. guttata in the undefined markings, slender bill, etc., but olivaceous-brownish instead of rufous above, the darker markings sepia-brown instead of castaneous. The white beneath much tinged with ashy; jugulum-spots blended, and of a sepia-brown tint. Wing, 3.00; tail, 3.00; bill .41 from nostril, and .25 deep at base.

      Hab. Northwest coast, from British Columbia northward. (Sitka.)

      The above characters are those of a large series of specimens from Sitka, and a few points along the coast to the southward and northward, and represent the average features of a race which is intermediate between guttata and insignis, in appearance as well as in habitat. Tracing this variety toward the Columbia River, it gradually passes into the former, and northward into the latter.

      We have no distinctive information relative to the habits of this race.

Melospiza melodia, var. insignis, BairdKODIAK 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.

      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, СКАЧАТЬ
