Mr. Ridgway calls this bird the “Rocky Mountain Hermit Thrush.” He states that he found it common in the Wahsatch Mountains, but that, on account of its retiring habits, it was seldom seen. It there lives chiefly in the deep ravines in the pine region, exhibiting an attachment to these solitudes rather than to the thickets along the watercourses lower down; the latter it leaves to the _T. swainsoni_. Owing to the reserved manners of this bird, as well as to the great difficulty of reaching its abode, there were few opportunities presented for learning much concerning its habits, nor did he hear its song. In its flight the pale ochraceous band across the bases of its quills was a very conspicuous feature in the appearance of its species, leading Mr. Ridgway to mistake it at first for the _Myiadestes townsendii_,—also an inhabitant of the same localities,—so much did it look like that bird, which it further resembled in its noiseless, gliding flight. SUBGENUS TURDUS, LINN. [Line drawing: _Turdus iliacus._ 1718] Of _Turdus_, in its most restricted sense, we have no purely American representatives, although it belongs to the fauna of the New World in consequence of one species occurring in Greenland, that meeting-ground of the birds of America and Europe; which, however, we include in the present work, as related much more closely to the former. This Greenland species, _Turdus iliacus_, is closely related to _T. viscivorus_, the type of the genus, and comes much closer to the American Robins (_Planesticus_) than to the Wood Thrushes (_Hylocichla_). Turdus iliacus, LINN. REDWING THRUSH. _Turdus iliacus_, LINN. Syst. Nat. 10th ed. 1758, 168, and of European authors.—REINHARDT, Ibis, 1861, 6 (Greenland). BAIRD, Rev. Am. B. 1864, 23 (Greenland). SP. CHAR. This species is smaller than our Robin (_T. migratorius_), but of a similar grayish-olive above, including the head. The under parts are white; the feathers of the lower throat and breast streaked with brown. The sides, axillars, and inner wing-covert are reddish-cinnamon. A conspicuous white streak over the eye and extending as far back as the nape. Bill black, yellow at base of lower jaw. Legs pale-colored. Second quill longer than fifth. Length, about 8.25; wing, 4.64; tail, 3.45; bill, from gape, 1.07; from nostril, .44; tarsus, 1.16; middle toe and claw, 1.15. Specimen described: 18,718, ♂, a British specimen received from the Royal Artillery Institution, Woolwich. HAB. Greenland, in the New World. The occurrence of this well-known European species in Greenland brings it within the limits of the American Fauna. Two Greenland specimens are recorded by Dr. Reinhardt: one of them shot at Frederickshaab, October 20, 1845. HABITS. The Redwing can probably only claim a place in the fauna of North America as an occasional visitant. Of the two specimens observed in Greenland, one was shot late in October. It is not known to breed there.
