Genus OTOCORYS

The genus Otocorys contains the Horned Larks, three species of which are found at considerable altitudes in the Himalayas. They occur in flocks, and at the breeding-season the males are said to rise in the air, and sing in the same manner as the Sky-Lark.

The Horned Larks have a few lengthened feathers springing from each side of the crown in both sexes. The bill is of median length, and the nostrils are densely covered by plumes ; the wing has nine primaries, of which the first reaches nearly to the tip of the wing; the hind claw is straight and about as long as the hind toe. The sexes are slightly different in colour, and both sexes undergo a considerable variation of plumage according to season, caused by the gradual wearing away of the margins of the feathers in winter and spring.
