The Hawfinch builds in various kinds of trees and at various heights; sometimes its nest is found quite exposed in a whitethorn bush, or on the horizontal branch of an oak. It is built of twigs, &c., intermixed with lichens, and interlined with fine fibrous roots and hair. Her eggs number from four to six, of a pale olive-green colour, irregularly streaked with dusky grey and spotted with black. The ground colour is variable, being sometimes of a buffish hue. THE STOCK DOVE. Clefts in rocks, rabbit-holes, cavities in the trunks of trees, and often on the ground beneath thick furze-bushes which are next door to waterproof on account of their thickness, are the situations chosen by the Stock Dove. Very little trouble is taken with the nest, which merely consists of a few twigs and roots. The eggs only number two, of a pure shining white. THE DARTFORD WARBLER. Thick furze-bushes are the places chosen by this bird for its nesting-place on the commons of Kent and Surrey. The materials used are dead branches of furze, moss, and dry grass mixed with wool, and lined inside with finer dead grasses, the whole structure being loosely put together. The eggs number four or five, and are of a greenish, sometimes buffish, white ground speckled all over with dark or olive-brown and cinereous, which become more dense at the larger end and form a zone. The eggs are at times more numerously spotted than at others; then the markings are not so large. THE POCHARD. This bird breeds in the east and south of England, also in Scotland and Ireland, although it is much less numerous during the summer than the winter months. The position of its nest is similar to that of the Wild Duck, also the materials of which it is composed (dead grass and sedge, as well as down when the bird has begun to sit). Its eggs number from seven even to thirteen, but ten is the usual number laid, of a greenish-buff colour. THE BLACK REDSTART. This well-known visitor breeds in many parts of Europe and North Africa, building a nest very similar to that of the Robin, composed chiefly of twigs, straw, dried grass, &c., and situated in holes of walls and other positions similar to the above-mentioned bird. Five is the usual number of eggs; however, four only, or as many as six, are found, generally pure white in colour, occasionally tinged faintly with brown. Cases are recorded where they have been found spotted at the larger end with minute brown spots. [Illustration: EGGS. 1. Spotted Fly-catcher. 2. Tree Sparrow. 3. Brambling. 4. Whinchat. 5. Scoter. 6.
