The nest of our Pied Wagtail is formed of moss, dead grass, and fibrous roots, lined with hair and a few feathers. It is sometimes placed on the bare ground on a ditch bank, sometimes in a hole of a wall, or thatch of an outbuilding, and it is frequently fixed in the side of a wood-stack or hay-rick; occasionally it has been found occupying a cavity in a peat-stack or a wall of turf sod, but always in the vicinity of water. The eggs are four or five in number, white, speckled with ash-colour, nine lines in length and seven lines in breadth.
Mr. Jesse, in his "Gleanings in Natural History," records an instance of a Water Wagtail building her nest in one of the workshops of a manufactory at Taunton:—"The room was occupied by braziers, and the noise produced by them was loud and incessant. The nest was built near the wheel of a lathe, which revolved within a foot of it. In this strange situation the bird hatched four young ones; but the male not having accustomed himself to such company, instead of feeding the nestlings himself, as is usual, carried such food as he collected to a certain spot on the roof, from whence it was borne by his mate to the young. It is still more remarkable that she was perfectly familiar with the men into whose shop she had intruded, and flew in and out of it without fear. If, by chance, a stranger or any other of the persons employed in the same factory entered the room, she would, if in her nest, instantly quit it, or, if absent, would not return; the moment, however, that they were gone she resumed her familiarity."
THE DHOBIN.
The DHOBIN (Motacilla Dukhunensis) is the Indian representative of the species just described. During the summer this bird is pale grey on the back and scapulars, a supercilian streak, the nape, wings, centre feathers of the tail, the throat, and breast, are black; the eyebrows, a spot on the wings, the exterior tail-feathers, and belly are white, and the secondary quills are dark grey, bordered with white. In the winter the chin, throat, and region of the eye, are white, and only a small black spot is visible on the breast; the top of the head and nape are then grey. The eye is brown, and the beak and feet black. The length of this species is from seven inches and a half to eight inches; the wing measures three inches and five-eighths; and the tail four inches and three-quarters.
The Dhobin is met with throughout the whole of Ceylon and Southern and Central India, and is very common in the Deccan; it usually makes its appearance in October, and remains till March or April. It is at present unknown where this species breeds; and we have but little information respecting its habits, except that it lives in close proximity to houses, frequently entering within doors to seize the flies as they skim about the rooms; during the day it remains solitary, but in the evening goes with its companions to the margin of some stream or other piece of water, there to pass the night.
This bird closely resembles the Motacilla alba of Europe, but is distinguished by its great ear patch, and by the blackness of the ear-feathers, and of the neck all round. "This Wagtail," says Jerdon, "is found throughout Southern and Central India, extending into the North-western Provinces, Sindh, the Punjaub, and Afghanistan. Adams, however, says that he did not see it in Peshawur, and that the former species is the Common Wagtail of Cashmere. It is also found in Ceylon. It is not very abundant in the extreme south of the peninsula, but is very common in the Deccan and in Central India, coming in about the middle of October and leaving in March or April. It is a very familiar bird, feeding close to houses, stables, and in gardens; often, indeed, entering verandahs, and coming into an open room if not disturbed. It runs about briskly after small insects, and is very active in catching the flies that infest the vicinity of stables and outhouses. A small party of these birds may often be seen towards evening on the bank of a river or tank, though, when feeding, they are usually solitary."
THE ROCK WAGTAIL.
The ROCK WAGTAIL (Motacilla Lichtensteinii) inhabits the valley of the Nile, and frequents such parts of that river as are traversed by rocks or huge masses of stone. Its plumage is simple but striking in its coloration; the entire mantle, sides of throat, and breast, are of a rich deep black; a stripe over the eyes, a patch on the throat, a spot on the wing-covers, the exterior tail-feathers, and under side are white; the eye is brown; the beak and feet black. In its movements this species closely resembles those of its family already described, but is distinguished from them by its habit of frequenting such portions of rock or stone as are entirely surrounded by water; in Nubia it is very common, but is rarely met with in any but the most stony districts. According to our own experience the Rock Wagtail lives in pairs, each couple keeping within the limits of its own domain, and violently resenting any attempt at intrusion. Like the rest of their brethren these birds are extremely quarrelsome, and live in a state of constant warfare with such of the northern species as take up their winter quarters in their vicinity. The nests which we found were always situated in holes or clefts in the rocks.
THE MOUNTAIN WAGTAIL.
The MOUNTAIN WAGTAIL (Calobates sulphurea) represents a group of Wagtails recognisable by their comparatively short wings, long tail, and delicate beak; the sexes also differ in the coloration of their plumage. During the spring the male is deep grey upon the back and sulphur-yellow on the under side; the black throat is divided from the grey back by a white line, a similar streak passes above the eyes, and the wing is enlivened by two light grey stripes; when quite old the females resemble their mates, but the yellow under side is of a paler hue, and the black on the throat less pale; when young, the females have only a white or dingy grey spot on the throat. The young of both sexes are of a dull ash-grey above and yellowish grey beneath, the throat is greyish black, spotted with blackish grey; the eye is dark brown, the beak black, and the foot horn-grey. This species is seven inches and two-thirds in length, and its breadth is nine inches and three-quarters; the wing measures three inches and a quarter, and the tail four inches.
