      Sp. Char. Wing much rounded; the second quill shorter than the secondaries. Tail much graduated. Bill much decurved, longer than the head. Above brownish-olive, without any shade of green; beneath pale cinnamon, lightest on the throat, deepening gradually into a brownish-rufous on the under tail-coverts. The fore part of the breast and sides of the body brown-olive, lighter than the back. An obscure ashy superciliary stripe, and another lighter beneath the eye. Ear-coverts and an indistinct maxillary stripe dark brown; the shafts of the former whitish. Ends and tips of tail-feathers obsoletely paler. Length, 11.50 inches; wing, 4.20; tail, 5.75; tarsus, 1.55.

      Hab. Coast region of California.

      Habits. The California Thrasher appears to have a somewhat restricted distribution, being confined to the coast region of California, where, however, it is quite abundant. It was first met with by Dr. Gambel, near Monterey. The specimens were obtained on the ground where they were searching for coleopterous insects. Dr. Heermann afterwards found this bird abundant in the southern part of California. It was difficult of approach, diving into the thick bushes, running some distance on the ground, and becoming afterwards unapproachable. He speaks of its song as a flood of melody equalled only by the song of the Mocking-Bird (Mimus polyglottus). Colonel McCall also describes its song as of exquisite sweetness, “placing it almost beyond rivalry among the countless songsters that enliven the woods of America.” He also states that it is as retiring and simple in its manners as it is brilliant in song.

      In the character of its flight it is said to strongly resemble the Brown Thrasher (H. rufus) of the Eastern States. Their harsh, scolding notes, when their nest is approached, their motions and attitudes, are all very similar to those of H. rufus under like circumstances. Colonel McCall ranks the song of this species as far superior to that of any other Thrush. Without possessing the powerful voice or imitative faculties of the Mocking-Bird, its notes are described as having a liquid mellowness of tone, with a clearness of expression and volubility of utterance that cannot be surpassed.

      A nest of this bird found by Dr. Heermann was composed of coarse twigs, and lined with slender roots, and not very carefully constructed. Mr. Hepburn writes that a nest found by him was in a thick bush about five feet from the ground. It was a very untidy affair, a mere platform of sticks, almost as carelessly put together as that of a pigeon, in which, though not in the centre, was a shallow depression about 4 inches in diameter, lined with fine roots and grass. It contained two eggs with a blue ground thickly covered with soot-colored spots confluent at the larger end, and in coloring not unlike those of the Turdus ustulatus. The eggs measured 1.19 inches by .81 of an inch. Dr. Cooper gives their measurement as 1.10 of an inch by .85. Two eggs belonging to the Smithsonian Institution (2,040, a and b) measure, one 1.19 by .81, the other 1.14 by .93. The former has a bluish-green ground sparsely spotted with olive-brown markings; the other has a ground of a light yellowish-green, with numerous spots of a russet brown.

      The general character of their nest is, as described, a coarse, rudely constructed platform of sticks and coarse grass and mosses, with but a very slight depression. Occasionally, however, nests of this bird are more carefully and elaborately made. One (13,072) obtained near Monterey, by Dr. Canfield, has a diameter of 6 inches, a height of 3, with an oblong-oval cavity 2 inches in depth. Its outside was an interweaving of leaves, stems, and mosses, and its lining fine long fibrous roots.

      These birds are chiefly found frequenting the dense chaparral that lines the hillsides of California valleys, forming thickets, composed of an almost impenetrable growth of thorny shrubs, and affording an inviting shelter. In such places they reside throughout the year, feeding upon insects, for the procuring of which their long curved bills are admirably adapted, as also upon the berries which generally abound in these places. Their nests usually contain three eggs. Dr. Cooper states that their loud and varied song is frequently intermingled with imitations of other birds, though the general impression appears to be that they are not imitative, and do not deserve to be called, as they often are, a mocking-bird.

Harporhynchus crissalis, HenryRED-VENTED THRASHER

      Harporhynchus crissalis, Henry, Pr. A. N. Sc. May, 1858.—Baird, Birds N. Am. 1858, 350, pl. lxxxii; Review, 47.—Cooper, Birds Cal. 1, 18.

      Sp. Char. Second quill about as long as the secondaries. Bill much curved; longer than the head. Above olive-brown, with a faint shade of gray; beneath nearly uniform brownish-gray, much paler than the back, passing insensibly into white on the chin; but the under tail-coverts dark brownish-rufous, and abruptly defined. There is a black maxillary stripe cutting off a white one above it. There do not appear to be any other stripes about the head. There are no bands on the wings, and the tips and outer edges of the tail-feathers are very inconspicuously lighter than the remaining portion. Length, 11 inches; wing, 4.00; tail, 5.80; tarsus, 1.25.

      Hab. Region of the Gila River, to Rocky Mountains; Southern Utah (St. George, Dr. Palmer).

      A second specimen (11,533) of this rare species is larger than the type, but otherwise agrees with it. Its dimensions are as follows:—

      Length before skinning, 12.50; of skin, 12.50; wing, 3.90; tail, 6.50; its graduation, 1.45; first quill, 1.50; second, .41; bill from forehead (chord of curve), 1.65, from gape, 1.75, from nostril, 1.30; curve of culmen, 1.62; height of bill at nostril, .22; tarsus, 1.30; middle toe and claw, 1.12.

      The bill of this species, though not quite so long as in redivivus, when most developed, is almost as much curved, and much more slender,—the depth at nostrils being but .22 instead of .26. The size of this specimen is equal to the largest of redivivus (3,932); the tail absolutely longer. The feet are, however, considerably smaller, the claws especially so; the tarsus measures but 1.30, instead of 1.52; the middle claw .29, instead of .36. With these differences in form, however, it would be impossible to separate the two generically.

      A third specimen (No. 60,958 ♀, St. George, Utah, June 9, 1870), with nest and eggs, has recently been obtained by Dr. Palmer. This specimen, being a female, is considerably smaller than the type, measuring only: wing, 3.90; tail, 6.00; bill, from nostril, 1.15. The plumage is in the burnt summer condition, and has a peculiar reddish cast.

      Habits. Of this rare Thrush little is known. So far as observed, its habits appear to be nearly identical with those of the Californian species (H. redivivus). It is found associated in the same localities with H. lecontei, which also it appears to very closely resemble in all respects, so far as observed. The first specimen was obtained by Dr. T. C. Henry, near Mimbres, and described by him in May, 1858, in the Proceedings of the Philadelphia Academy of Sciences. СКАЧАТЬ
