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.
This species, during its breeding season, is found only in the more northern portions of Europe; only occasionally, and very rarely, breeding so far south as England. It makes its appearance in that kingdom on its southern migrations, coming in large flocks from Northern and Northeastern Europe, and arriving usually before the end of October. During their stay in England they frequent parks and pleasure-grounds that are ornamented with clumps of trees. During mild and open weather they seek their subsistence in pasture lands and moist meadows, feeding principally on worms and snails. In severe winters, when the ground is closed by frost or covered by snow, the Redwings are among the first birds to suffer, and often perish in large numbers.
During the winter they extend their migrations to the more southern portions of Europe, to Sicily, Malta, and even to Smyrna. In early spring they return to the more central portions of the continent, and leave in May for their more northern places of resort.
They nest in trees in the moist woods of Norway and Sweden. Their nests resemble those of the common Fieldfare, T. pilaris. The outside is composed of sticks, weeds, and coarse grass, gathered wet, and matted with a small quantity of moist clay. They are lined with a thick bed of fine grass.
The Redwing is said to possess a delightful note, and is called the Nightingale of Norway. Linnæus, speaking of this bird, claims that its high and varied notes rival even those of that far-famed vocalist.
During the summer the Redwing advances to the extreme north, visiting the Faroe Islands, Iceland, and Northern Russia. The general character of its food, its inability to feed exclusively on berries, and the fact that it perishes from starvation in severe winters, would seem to prove that its occurrence in Greenland so late as October must have been purely accidental. It is not probable that its presence in North America will be found to be a common event.
The eggs measure 1.06 inches in length by .81 in breadth. The ground color is a light green with a bluish tinge thickly covered with russet or reddish-brown spots, confluent at the larger end.

This section of the Thrushes is well represented in America, especially in its middle and southern portions, and its members have a close resemblance to the typical European species in the full form, stout legs, etc., as already stated. The spots on the throat, and their absence elsewhere on the under part of the body, are sufficient to distinguish them.
Of the two North American species one is the well-known Robin, the other a closely related form from Cape St. Lucas; which indeed is probably only a local race or variety, although nothing exactly like it has yet been found away from Lower California. The following diagnosis may serve to distinguish the two birds:—
Common Characters. Throat white with dark streaks. Rest of under parts, including lining of wing, reddish or ochraceous; the anal region whitish; lower eyelid white. Nest on trees. Eggs plain blue.
Above slaty-olive, approaching to black on the head. Beneath rufous-chestnut. Spot in lore and on upper eyelid of white. Tail, 4.25. Hab. Whole of North America; Mexico, south to Oaxaca and Cordova; Cuba (very rare) and Tobago, of West Indies … var. migratorius.
Above dull grayish-ash, not darker on the head. Beneath pale yellowish-buff; tinged with ashy across breast; a continuous white stripe from the lores over and a quarter of an inch behind the eye. More white on belly and flanks than in T. migratorius. Bill stouter; tail only 3.75, while the wing is the same. Hab. Cape St. Lucas, Lower California … var. confinis.

Sp. Char. Tail slightly rounded. Above olive-gray; top and sides of the head black. Chin and throat white, streaked with black. Eyelids, and a spot above the eye anteriorly, white. Under parts and inside of the wings, chestnut-brown. The under tail-coverts and anal region, with tibiæ, white, showing the plumbeous inner portions of the feathers. Wings dark brown, the feathers all edged more or less with pale ash. Tail still darker, the extreme feathers tipped with white. Bill yellow, dusky along the ridge and at the tip. Length, 9.75; wing, 5.43; tail, 4.75; tarsus, 1.25.
Hab. The whole of North America; Mexico, Oaxaca, and Cordova; Guatemala; Cuba, very rare, Gundlach; Tobago, Kirk; Bermuda, Jones; Orizaba (Alpine regions, breeding abundantly), Sumichrast.
Young birds have transverse blackish bars on the back, and blackish spots beneath. The shafts of the lesser coverts are streaked with brownish-yellow; the back feathers with white.
Turdus migratorius.
There are some variations, both of color and proportions, between eastern and western specimens of the Robin. In the latter there is a tendency to a longer tail, though the difference is not marked; and, as a rule, they slightly exceed eastern specimens in size. The broad white tip to the lateral tail-feather—so conspicuous a mark of eastern birds—is scarcely to be found at all in any western ones; and in the latter the black of the head is very sharply defined against the lighter, clearer ash of the back, there hardly ever being a tendency in it to continue backward in the form of central spots to the feathers, as is almost constantly seen in eastern examples; of western specimens, the rufous, too, is appreciably lighter than in eastern. As regards the streaks on the throat, the black or the white may either largely predominate in specimens from one locality.
In autumn and winter each rufous feather beneath is bordered by a more or less conspicuous crescent of white; in addition to this, most of the lighter individuals (♀?), at this season, have an ashy suffusion over the breast and flanks; and this, we have observed, is more general and more noticeable in western than in eastern specimens. In fall and winter the color of the bill, too, changes, becoming at this season either partially or wholly dusky, instead of almost entirely yellow, as seen in spring and summer examples.
Mexican specimens, found breeding in the Alpine regions as far south as Orizaba and Mirador, most resemble the western series; one, however (No. 38,120 ♂, Orizaba), but in the autumnal plumage, and therefore very possibly a migrant from the North, is hardly distinguishable from No. 32,206, Georgia; it is about identical in proportions, and the rufous is of a castaneous shade, like the deepest colored eastern examples; the white tip to the outer tail-feather is as broad and conspicuous as is ever seen in the latter.
Habits. Scarcely any American bird has a wider range of geographical distribution, or is more numerous wherever found, than this thrush. From Greenland on the extreme northeast to the plateau of Mexico, and from the Atlantic to the Pacific, the Robin is everywhere a very abundant species. Single specimens have been obtained as far south as Coban, Guatemala. Its distribution in the breeding season is hardly less restricted, occurring alike on the shores of
