HABITS. The common White Wagtail of Europe claims a place in the North American fauna as an occasional visitant of Greenland, where in two instances single specimens have been procured. It is found in all portions of the European Continent, from the islands of the Mediterranean as far north as the Arctic regions. It appears in Sweden in April, and leaves there in October. Mr. Gould states also that it is found in the northern portions of Africa, and in the highlands of India. It also occurs, though less frequently, in England, where it is replaced by a local race, or an allied species, _Motacilla yarrelli_ of Gould. The _Motacilla alba_ is said by Temminck to inhabit meadows in the vicinity of streams of water, villages, and old houses. Its food is chiefly insects in various stages and of different kinds. It builds its nest on the ground among the grass of the meadow, in fissures in rocks or decayed buildings, among the roots of trees, on the banks of streams, in piles of wood and fagots, or under the arch of a bridge. The nests are somewhat coarsely constructed of interwoven dry bent stems of plants and reeds, with a finer lining of the same. The eggs, six in number, are of a bluish-white ground thickly sprinkled with fine dottings, which are most usually of a blackish-brown color, sometimes ashy-gray or reddish-brown. The Pied Wagtail, _M. yarrelli_, Degland and Gerbe regard as a race, and not a species. It has a limited habitat, confined to Norway, Sweden, and the British Islands, in the latter of which it is a resident throughout the year. Besides their difference in plumage, Mr. Yarrell has noticed certain differences also of habit. The _alba_ is said not to be so partial to water as the pied species, and though often found near ploughed land, does not, like its kindred species, follow the plough in search of insects. Mr. Hewitson also states that it has a hoarser voice. Like all the birds of this family, the Wagtail is much admired for the elegance of its form, its activity, and the airy lightness of its motions. It seems ever on the move, runs with great rapidity a quick succession of steps in pursuit of its food, and goes from place to place in short undulating flights. It has a cheerful chirping note which it utters while on the wing. When it alights, it gives a graceful fanning movement with its tail, from which it derives its name. The Pied Wagtail, whose habits have been more closely observed by English naturalists, has frequently been seen to wade into the water in search of aquatic insects, and probably also of small fish, as in confinement they have been known to catch and feed on minnows in a fountain in the centre of their aviary. It is probable that the habits of the White Wagtail are not dissimilar. They leave their breeding-places in October, collecting and moving in small flocks.
