The nest of the thrush (Fig. 197) is a massive structure, deep and cup-shaped, and open at the top. It is built of small twigs and grass, and is plastered with mud or cow-dung until the inside is smooth and hard. It is usually placed in an evergreen bush or tree, but may also be found in cavities in tree-trunks or in holes in walls, or even in sheltered places on the ground. The eggs number from 4 to 6; they are about an inch long, are sky-blue in colour, and marked with black spots, which are most numerous near the thick end. The eggs are arranged with their pointed ends inwards; this method not only allows them to be packed more closely together and therefore to be more easily [Pg 306] covered by the sitting bird, but is also of convenience at the time of hatching, as the young birds usually emerge (p. 294) at the thick end. The eggs hatch after a fortnight’s incubation. The young thrushes are at first blind, almost naked, and are quite helpless. They make rapid progress, however, and are sufficiently fledged to leave the nest in about a fortnight after hatching. The fledgling throstle (Fig. 198) is lighter in colour than the adult, and much more distinctly spotted. In October the young birds may be heard learning to sing; their first efforts are hesitating and uncertain, but by tireless practice and careful imitation of the old birds they presently come into full possession of their delightful powers. Fig. 198.—Young Song-Thrushes in Nest. The missel, or mistletoe, thrush (Fig. 199) much resembles the song-thrush in appearance and manner of life, but is distinctly larger, measuring about 10½ inches from head to tail. It has a very pleasing song, which may be heard, even in the depth of winter, [Pg 307] when all other song-birds are mute. The missel thrush’s habit of singing vigorously during storms has led to its alternative name of “storm-cock.” The bird is noted for its pugnacity in the breeding season, and for the courage with which it defends its nest and young; any other birds approaching the nest are promptly attacked and driven to a distance. The nest is generally built in a tree, where a branch springs from the trunk. It is made of dried grass, moss, and wool, and the hen lays from 4 to 6 pale-green eggs, which are speckled with brown.
