So far as the British Isles are concerned, it is perhaps only safe to say that this bird breeds at St. Kilda, although it has been reported from other quarters. Its nest is situated on ledges of cliffs covered with a sufficient amount of earth for the bird to make a burrow in, or in crevices. It is sometimes lined with a scanty supply of dry grass; at others no lining at all is used. The bird lays a single rough, chalky-white egg. THE GARGANEY. Norfolk seems to be the last breeding resort of this duck. Its nest is situated in reed beds, or such other vegetation as will afford the bird plenty of concealment. It is composed of reeds, leaves, or dry grass, and is lined with pieces of down, the long white tips of which distinguish it from the Teal. The eggs are creamy-white, like those of the bird above-named, and number from seven or eight to as many as thirteen. THE GOOSANDER. The Goosander breeds in the Highlands of Scotland, and situates its nest in hollow trees and crevices of rock, generally near the water. Very little, if any, material is said to be used excepting the warm lining of greyish-white down from the bird's own body. The eggs number from eight to a dozen or thirteen, creamy-white and smooth-shelled. THE GREAT CRESTED GREBE. The midland and eastern counties contain the favourite breeding resorts of this handsome bird. Its nest is composed of all kinds of dead aquatic vegetation, such as reeds and flags, and is situated in or on the water of lakes, broads, large tarns, and meres. The bird lays three or four eggs, sometimes even as many as five, white and chalky when first laid, but soon becoming soiled and dirty. THE BLACK GUILLEMOT. The Isle of Man, Hebrides, Orkneys, Shetlands, and some parts of Ireland are favoured by this bird as a breeder. Its nest is situated in crevices and under ledges and boulders of rock. No materials of any kind are used for its nest. The eggs number two, varying from light bluish-green to light buffy-white in ground colour, spotted, speckled, and blotched with rich blackish-brown and pale reddish-brown and underlying grey markings. THE KITTIWAKE. The nest of the Kittiwake is situated on ledges of maritime cliffs round our coast, and at the Farne Islands. I have seen the bird occupying such a small corner that it was unable to sit properly on its eggs. The nest is made of seaweed and lined with dead grass. Its eggs number two, three, and rarely four, and vary from light greenish-blue to stone colour, or buffish-brown, blotched and spotted with varying shades of brown and grey. The markings sometimes form a zone round the larger end. THE SHORT-EARED OWL. On the ground, amongst heather or sedges, this bird makes its nest, in the eastern and northern counties and in Scotland. It uses next to no materials, but such as are present consist of bits of dead reeds and leaves. Its eggs number from four to seven or eight, pure white, unspotted, and oval in shape. THE LESSER SPOTTED WOODPECKER.
