Like the Pied Wagtail the Budytes Rayi is always actively insects ; like that species, too, it affects the immediate precincts of cattle, but sometimes suddenly pitches on our lawns and gardens. It is certainly much less aquatic in its habits than either the Grey Wagtail (Calobates sulphurea) or the typical Motacille (M. Yarrellii and M. alba). In structure it approaches the true Pipits (Andi), and also resorts to the same kind of situations for which those birds evince a preference. It breeds on the ground, among the growing corn, in fields of peas, in a grass-field, on a naked fallow, or by the ditch-side. ‘‘ The nest,” says Mr. Hewitson, ‘is composed of dry grasses, is lined with finer grasses and roots, and a few hairs. Mr. Newton tells me that it varies very much in the materials of which it is composed: ‘One of two nests taken on the same day, and within a few yards of each other, was composed of green moss and grass, lined with rabbit’s down, the other entirely of grass, lined with fine roots.’ The eggs are usually four or five in number, occasionally six ; they are generally somewhat less than those of the Grey Wagtail, which they sometimes resemble, but they are mostly more like those of the Grey-headed Wagtail ; and it would be very difficult to identify them if once mixed with the eggs of the Sedge-Warbler, which they closely resemble in colour, as well as in being usually marked with a black roots, bits of moss or wool, and waved line across the larger end.” The sexes differ materially in colour, the face, throat, and under surface of the female being merely washed with a lighter colour than that which is so conspicuous in the male. The young are spotted and speckled on the wings and a portion of the upper surface, in which state they resemble young Pipits. The Plate represents a male and a female, of the size of life.
