Like some other of the Hawks, the Merlin does not take much trouble in the construction of her nest, simply selecting a little hollow, usually well hidden by heather, in moorland districts, lining it with dead ling and a little grass. The eggs number from three to six, according to some authorities; but I have usually found four on the North Riding moors, brown in colour, thickly covered with spots, blotches, and marblings of a reddish hue, especially at the larger end. THE BITTERN. The ground is chosen as the situation of this bird's nest, well hidden amongst the dense growth of reeds and flags, in close proximity to the water it haunts. It is composed of a plenteous supply of sticks, reeds, flag-leaves, &c. The eggs are found in numbers of from three to five, and have been described as of a pale clay-brown, stone colour, and olive-brown, all of which are as near the mark as a verbal description can come. THE NIGHT-JAR. This bird cannot really be said to make a nest of any kind, simply selecting some natural depression in the earth, beneath the shelter of a furze-bush or common bracken. She lays two eggs, which are grey, beautifully spotted, and marbled or veined with dark brown and tints of a bluish-lead colour, glossy. The female sits so closely, and harmonises so well with her surroundings, that, unless one happens to detect her beautiful large eye, the chances are very much against finding her nest. THE STORM PETREL. The Scilly Islands, St. Kilda, the Orkneys, Shetland, and the Irish coast, are the breeding haunts of the Storm Petrel. The nest is placed on the ground, amongst cliffs and under large-sized stones, being composed of pieces of dry earth and stalks of plants. One single white egg, about the size of a Blackbird's, is laid. THE STONE-CHAT. This pert little bird is very dexterous in the art of nest-building, selecting for materials moss and dry grasses to form the outer structure, and feathers, hair, &c., for lining the interior. The position selected is generally on the ground, at the bottom of a furze-bush, though sometimes quite away from any bush. The eggs number five or six, and are of a pale blue-green, with minute reddish-brown spots, chiefly at the larger end. THE WHEAT-EAR. A sheltered and darkened situation is generally chosen by the Wheat-ear wherein to build her nest--chinks of stone walls, the ruins of cairns, in old rabbit-burrows, under stones on moors, mountain wilds, &c. The nest, not very artistic in construction, is composed of a variety of materials, such as bents, grass roots pulled up by the sheep when grazing, and dried in the sun, hair and wool gathered from brambles, corners of rocks, and walls against which the sheep have rubbed themselves. The eggs number five or six, and are of a pale greenish-blue colour unspotted.
