СКАЧАТЬ the most soft and plaintive notes of woe. The nest is embedded in the moss to its edges, and is composed of fine grasses, circularly disposed and forming a bed about two inches thick. It is lined with the feathers of the grouse and of other birds. The eggs, deposited early in July, are four or five in number, and are described by Mr. Audubon as marked with bluish as well as brown spots.

      About a week before they can fly, the young leave the nest, and follow their parents over these beds of mosses to be fed. They run nimbly, and squat closely at the first approach of danger. If observed and pursued, they open their wings and flutter off with great celerity.

      These birds reach Labrador early in June, when the male birds are very pugnacious, and engage frequently in very singular fights, in which often several others besides the first parties join, fluttering, biting, and tumbling over in the manner of the European House Sparrow. The male is described as singing sweetly while on the wing, but its song is comparatively short. It will also sing while on the ground, but less frequently, and with less fulness. Its call-note is quite mellow, and is at times so altered, in a ventriloquial manner, as to seem like that of another bird. As soon as the young are hatched their song ceases. It is said to feed on grass-seeds, the blossoms of small plants, and insects, often catching the latter on the wing, and following them to a considerable distance. It also gathers minute crustaceans on the sea-shore.

      Mr. Ridgway found this species abundant over the arid wastes of the interior, and, in many localities, it was almost the only bird to be found. In its habits he could observe no differences between this bird and the alpestris. He met with their nests and eggs in the Truckee Reservation, June 3. The nest was embedded in the hard, grassy ground, beneath a small scraggy sage-bush, on the mesa, between the river and the mountains.

      Mr. J. K. Lord mentions that, having encamped at Cedar Springs on the Great Plains of the Columbia, where the small stream was the only water within a long distance, he became interested in watching the movements of these Larks. As evening approached they came boldly in among the mules and men, intense thirst overcoming all sense of fear. He found these handsome little birds very plentiful throughout British Columbia. They were nesting very early on those sandy plains, even before the snow had left the ground. He saw young fledglings early in May.

      A single specimen of this species was taken at Godhaab, Greenland, in October, 1835.

      Eggs from Labrador are much larger in size than those from Wisconsin. Two eggs from the first, one obtained by Mr. Thienemann, the other by Mr. George Peck, of Burlington, Vt., measure .93 and .94 of an inch in length by .71 in breadth; while some from the West are only .83 in length and .63 in breadth, their greatest length being .90, and their largest breadth .69 of an inch. In their ground-color and markings, eggs from both localities vary about alike. The ground-color varies from a purplish-white to a dark gray, while the spots are in some a brownish-lavender, in others a brown, and, quite frequently, an olive-brown. In some they are in larger, scattered blotches; while in others they are in very fine minute dots so thickly and so uniformly diffused as almost to conceal the ground.

      Winter plumage. Rusty prevailing above, but hoary whitish edges to feathers still in strong contrast; streaks beneath with a rufous suffusion externally, but still with the black in excess.

      Winter plumage. Gray above more olivaceous, the black streaks more subdued by a rufous suffusion; streaks beneath with the rufous predominating, sometimes without any black.

      Winter plumage. Above rusty-olive, with little or no ashy, the black streaks broad and distinct. Streaks beneath with the black and rusty in about equal amount.

      In summer the streaks beneath are entirely intense black; in winter they have a slight rufous external suffusion.

Sp. Char. (Type, 60,046, Puebla, Mexico, A. Boucard.) Similar to M. melodia, but ground-color above olive-brown; inner webs of interscapulars pale ashy, but not in strong contrast. Crown and wings rusty-brown, the former with broad black streaks, and divided by a just appreciable paler line; back with broad black streaks without any rufous suffusion. Superciliary stripe pure light ash, becoming white anterior to the eye; two broad, dark-brown stripes on side of head,—one from the eye back along upper edge of auriculars, the other back from the rictus, along their lower border. Lower parts pure white, the flanks and crissum distinctly ochraceous; markings beneath broad and heavy, entirely pure deep black; those on the jugulum deltoid, on the sides linear. Wing, 2.60; СКАЧАТЬ
