abounding in lofty trees or pine and fir forests are the localities they prefer. The nest is formed of moss, stalks, lichens, and grass; the outer wall being frequently coated with a layer of mud, and the interior neatly lined with fine grass and similar materials. (The egg is represented in Fig. 12, Coloured Plate XVI.) The voice of the Missel Thrush resembles that of the Blackbird. "The male," says Mudie, "is not a mere idle songster; he is equally vigilant and bold in the defence of his family. The call-note he utters in case of danger--and which is answered by the female as if she were expressing her confidence of safety while he is on the watch--is harsh, grating, and has the tone of a note of defiance. With the Missel Thrush this defiance is no idle boast, for the sneaking Magpie, the light-winged Kestrel, and even the Sparrow Hawk, are at those times compelled to keep their distance, as the Thrush is too vigilant to be taken by surprise, and under the sprays where these birds contend with him on equal terms he keeps them all at bay. Nor is he the guardian of his own family only--he is in some measure the warder of the whole grove, and when the harsh but shrill sound of his bugle-note of alarm is heard, all the warblers take heed of the danger, and the chorus is mute until he again mounts the highest branch and raises the song of thankfulness for deliverance." THE SONG THRUSH. The SONG THRUSH (_Turdus musicus_) is considerably smaller than the Missel Thrush, its length being eight inches and a half, and its breadth twelve and three-quarters; its wing measures four inches and one-sixth, and its tail three inches and a quarter. The upper portion of the body is olive-grey, the under side yellowish white, marked with triangular oval brown spots, which are less numerous on the belly than in the species above described; the lower wing-covers are also palish yellow, instead of white, and the feathers on the upper covers tipped with dirty reddish yellow. The sexes differ only in their size; the young are recognisable by the yellowish streaks and brown spots on the tips of the feathers of the upper part of their body. Like the Missel Thrush, this species inhabits the whole of Europe, being, however, especially numerous in its extreme north, and rarely breeding in the most southern portions of the continent, which are usually only visited during the winter months; it is also frequently met with in China, and during its migrations wanders as far as North-western Africa, but is rarely seen in the north-eastern provinces of that continent. Notwithstanding the very quarrelsome disposition usually displayed by these birds, many interesting anecdotes have been recorded concerning the great affection they display towards each other. Amongst these Yarrell mentions a touching instance, related by Mr. Knapp:--"We observed," says the latter, "two common Thrushes frequenting the shrubs on the green in our garden; from the slenderness
