      Habits. The famed Skylark of the Old World can rest a twofold claim to be included in a complete list of North American birds. One of these is their occasional occurrence in the Bermudas, and in Greenland. The other is their probably successful introduction near New York.

      A few years since an attempt was made to introduce these birds, for which purpose several individuals were set at liberty on Long Island. For a short time they did well, and succeeded in raising one or more broods, but, owing probably to the constant persecution of all small birds by the foreign population of the neighborhood, the experiment nearly failed, and none were noticed in that vicinity. Within the last year or two, however, several pairs of these birds have been observed in Westchester County, and also on Long Island, by parties competent to recognize them, and hopes are now entertained that these desirable birds have obtained a foothold in this country.

      According to Messrs. Dresser and Sharpe, the Skylark is found throughout the polar Arctic regions, from the British Islands eastward to Siberia and Northern China. A smaller subspecies is met with in Southeastern Europe, which does not present any character by which it can be separated from it. In Eastern Europe the Lark has been found as far north as the Faroe Islands, but has not been observed in Iceland. It reaches Christiania in March, and leaves in October. It has been found breeding in Lapland as far north as latitude 65°, and is a common summer visitant in Finland. Pallas found it abundant throughout Russia and Siberia, and Steller found it not only in Kamtschatka, but equally in the Kurile Islands and in those between Asia and America, so that its occurrence in our Alaskan territories may be regarded as a not improbable event.

      The same writers also state that the Skylark has been twice recorded as occurring in Greenland and in America; and in another place they state that “the Skylark occasionally visits Greenland, and has been met with in the Bermudas.” In the latter place a storm-tried waif was taken by Mr. J. M. Jones after an easterly gale.

      The Lark is a universal favorite in the Old World, and as a vocalist enjoys a reputation hardly second even to the far-famed Nightingale. It is an inhabitant of all the countries of Europe, and is said to be most abundant in the cultivated districts.

      We only know of its song from caged specimens and from the testimony of European writers. Yarrell speaks of its notes as cheerful and exhilarating, fresh as the season of spring, and the admiration of all hearers. Its voice is described as powerful to an extraordinary degree, and its song wild and joyous. They sing while they fly, rising, with quivering wings almost perpendicularly, until they gain so great an elevation that they can no longer be distinguished; yet, while thus no longer visible, their wild music continues to be heard as that of some unseen spirits of the air. It is said that one familiar with their song can readily determine, by their notes, whether the singer is ascending, stationary, or descending. Occasionally, when at this great elevation, the Lark will close its wings and drop to the earth with the rapidity of a stone. At times it will sing while on the ground, but its most lively strains are poured forth during these flights. And though this bird will sing while in confinement, and is a favorite cage-bird, yet in singing they are said to flutter their wings, as if this motion were almost a necessary accompaniment to their song.

      In regard to the song and its peculiarities writers are not quite in agreement. The general opinion seems to be that, while in the quality of its tone it is surpassed by the song of the Nightingale, the Bulfinch, and the Black-cap, it is unequalled in quantity, sprightliness, variety, and power. The Lark is in song eight months of the year, and during the summer months it sings from two in the morning, with very little intermission, until after sunset.

      Mr. Macgillivray gives an excellent and graphic description of the habits of this bird, from which we extract a portion descriptive of its song. “It has been alleged,” he writes, “that the Lark ascends in a spiral manner, but my observation does not corroborate the statement. In rising it often passes directly upward, but with the body always horizontal, or nearly so, then moves in a curve, and continues thus alternately, but without a continued spiral motion. At first, the motion of the wings is uniformly fluttering; but afterwards it shoots them out two or three times successively at intervals, and when at its greatest height exhibits this action more remarkably. When it descends, the song is not intermitted, but is continued until it approaches the ground, when it usually darts down headlong, and alights abruptly. Frequently it resumes its song after alighting, and continues it for a short time, but more commonly it stops when it has reached the ground. Often a Lark may be seen hovering over a field, in full song, for a considerable time, at a small height. On the 4th of May, 1837, I observed a Lark perched on a half-burnt whin branch, where it remained singing a long time. I have often seen it perch on a wall, and several times on a hawthorn bush in a hedge; but it never, I believe, alights on tall trees.

      “The song of the Lark is certainly not musical, for its notes are not finely modulated, nor its tones mellow; but it is cheerful and cheering in the highest degree, and protracted beyond all comparison. In a sunny day in April or May, when the grass-fields have begun to resume their verdure, it is pleasant to listen to the merry songster that makes the welkin ring with its sprightly notes; in the sultry month of July, still more pleasant is it to hear its matin hymn while the dew is yet on the corn; and in winter, should you chance to hear the well-known voice on high, it reminds you of the bright days that have gone, and fills you with anticipation of those that are to come. No doubt much of the pleasure derived from the Lark’s song depends upon association, but independently of circumstances and associations the song of the Lark imparts an elasticity to the mind, elevates the spirits, and suspends for a time the gnawing of corroding care. The carol of the Lark, like the lively fife, excites pure cheerfulness. In confinement this bird sings every whit as well as when at large, and when rapidly perambulating the square bit of faded turf in its cage, it enacts its part with apparently as much delight as when mounting toward heaven’s gate.”

      This bird succeeds well in cages, and lives to a great age, Yarrell mentioning one that lived nearly twenty years in confinement. Its natural food is grain, the seeds of grasses, worms, and various kinds of insects. They begin to mate in April, and have two broods in a season. Their nest is always placed on the ground, often sheltered by a tuft of grass, or some other protection. The nests are woven of coarse grasses and stems of plants, and are lined with finer materials of the same. The eggs are five in number, have a grayish-white ground, occasionally a greenish-white,
