The Dipper, or Water Ouzel as it is called in some districts, builds her nest in such splendid harmony with its surroundings that it is very difficult to find. It is generally placed near to some waterfall, and very often behind it, so that the bird has to fly through the water on entering and leaving her nest. It is also found in caves, underneath the arches of bridges, and I have even found one in a tree. The exterior is composed of aquatic mosses, and the interior beautifully lined with dry leaves. Dippers' nests are generally of large size, almost globular in form, with a central hole for the entrance and exit of the bird. She lays from four to six eggs, the average being five, of a delicate semi-transparent white, unspotted. [Illustration: EGGS. 1. Dipper. 2. Garden Warbler. 3. Missel Thrush. 4. Spoonbill. 5.

The Garden Warbler's nest is located a few feet from the ground, in the branches of a thorn or bramble-bush, and coarse grasses, which are densely matted. It is made of straws, dried grass, fibrous roots, wool, and horsehair, and is rather loose and slovenly. Her eggs number four or five, of a pale yellowish stone-grey, blotched and spotted with ash-grey and purplish-brown. THE MISSEL THRUSH. This bird, known in many parts of the country as the Misseltoe Thrush, builds her nest in trees, resting it on a branch close to the trunk, or where the trunk ends abruptly in two or three strong branches. It is composed of dried grass and moss, with a liberal mixture of wool, which helps it to adhere to the bark of the tree, and is lined internally with fine soft grass. Her eggs number from four to six, according to some authorities, of a pale green, speckled with brown, of two shades; however, the colours are subject to variation. She commences to breed very early in the season, like the Common Thrush, and has been known to lay twice in the same nest, which strengthens my opinion that the bird does often rear two broods in one season, from the time I have known her to occupy the same nest. THE SPOONBILL. The Spoonbill lays from two to four eggs, which vary in colour, some being entirely white, whilst others are spotted with a light brownish-red. The nest is situated in trees, or amongst the reeds and rushes on the ground, the bird seeming, like the Heron, partial to society. If the nature of the position will permit, several nests are situated close together, and are composed of sticks, coarse grass, and dried roots, carelessly thrown together. The bird does not breed in this country. THE PTARMIGAN. This bird lays from six to fifteen eggs of a pale red, brown or white, blotched with two shades of darker brown. Her nest is situated on the ground, on the bleak stony mountain-tops of the mainland of Scotland and the surrounding islands. It is merely a cavity scratched in the ground, in which the hen lays her eggs.
