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. FAMILY ICTERIDÆ.—THE ORIOLES.
