THE DESERT LARK (Ammomanes deserti).
This lively, elegant little bird is found extensively in all the African lowlands, beyond sixteen degrees north latitude, flying about freely in the immediate vicinity of man, and only avoiding such localities as high mountains or dense forests. In its habits it is by no means so brisk and alert as the Desert Lark, and its appearance anything but trim, as it runs or sits with drooping head, and wings hanging loosely from its side; but its flight is easy, and its movements when upon the ground far from clumsy, and very rapid. Its song is extremely simple, consisting generally of a monotonous repetition of the syllables tit-tit, and is uttered both when perched and when upon the wing. Our knowledge respecting the incubation of this species is extremely scanty, and we can only say that the little mates are much attached to each other, keep themselves separate from their kindred during the breeding season, and rejoin them when their parental duties are accomplished, forming parties which occasionally become very numerous. The plumage of the young differs considerably from that of the adult birds.
THE ALPINE LARK.
The Alpine Lark, or Shore Lark (Phileremos alpestris), is one of the liveliest members of its family, both as relates to its plumage and disposition, and may be regarded as forming, with a few other species, a distinct group remarkable for the elongation of the body, and two appendages resembling feathery horns, with which the back of the head is furnished. The beak is straight, weak, and of moderate size; the wings long, with the second, third, and fourth primaries almost of equal length; the feet are strong, the toes of moderate size, and the hinder toe armed with a slightly curved, spur-like claw. The plumage of this bird is variegated in its tints; the length of its body is about seven inches, the breadth thirteen; the wings measure four, and the tail three inches. The Alpine Lark is an inhabitant of Northern Europe, and is easily recognisable by its elegant and striking appearance. Upon the back the feathers are of a reddish grey; the wings and tail black, bordered with dark brown; the breast and belly of a very pale yellowish grey, so light as to be nearly white. The markings upon the head are extremely beautiful: the brow is of a dull yellow, the region of the ear yellowish grey, enlivened by a bright brimstone-coloured line, which passes over the eyes, and gradually spreads till the throat and sides of the neck are of the same colour. The upper part of the breast is decorated with a triangular patch of velvety black, the cheeks, base of the beak, a streak upon the head, and the tufts being of the same rich deep shade. The eye is light brown, the beak and feet of a blueish tint. The coat of the nestlings is of a pale brownish grey upon the back, all the feathers edged with light yellow; the belly is white, and the individual feathers furnished with a pale yellow border; the wing and tail feathers are brown.
THE ALPINE LARK (Phileremos alpestris).
The name of the Alpine Lark is derived, not from the Swiss Alps, but from the mountains of Siberia, and the rest of Northern Europe, where, at the present day, it is met with in large numbers, though until within the last fifty years it was considered to be one of the rarest birds in our continent. According to our own observations, this species is not found at a greater elevation than 400 or 500 feet above the level of the sea. In Lapland it lives near the coast. These Larks quit the more northern countries at the end of October, and return about April, when they at once commence preparations for their young. The nest is most carefully constructed, and neatly lined with fine blades of grass, cotton wool, and other delicate materials, a slight hollow being prepared in the ground for its reception; in this the little cradle is so well concealed as to be only discoverable by a practised eye. The brood consists of from four to five eggs, of about the same size as those of the common Field Lark; they are usually yellow, and covered with very fine markings of a deeper shade, which take the form of a wreath around the broadest end; varieties are, however, occasionally found exhibiting grey streaks, or brown hair-like lines. In its habits this species closely resembles the Field Lark; indeed, the movements of the two are so exactly similar as to render it almost impossible to distinguish between them, either when on the ground or in the air: the Alpine Lark, however, sings either when perched or sitting upon a stone, and not, like its more southern representative the Field Lark, only when soaring in the air. It subsists chiefly upon seeds and insects, feeding its young principally upon the gnats and larvæ abounding in its favourite resorts.
The LARKS PROPER (Alauda) are distinguished from the birds just described by their more slender beaks, short wings, and simple plumage, but closely resemble them in other particulars.
