A migratory species visiting this country about the latter end of April or beginning of May, and departing in the Autumn. Is most abundant in the southern, midland, and eastern counties. Frequents heaths, extensive corn-lands, and other open districts. Feeds on insects, worms, and reptiles. Makes no nest, but lays its eggs, which are two in number, on the bare ground. During the breeding season the male utters a loud shrill cry, heard more particularly in the dusk of the evening. The name of this species is derived from a peculiar enlargement of the upper part of the tarsus, and of the joint immediately above it, most conspicuous in the young birds of the year.
