To men of science these birds are known as babblers. Babblers proper are essentially birds of the plains. In the hills they are replaced by their cousins, the laughing-thrushes. Laughing-thrushes are merely glorified babblers. The Himalayan streaked laughing-thrush (_Trochalopterum lineatum_) is one of the commonest of the birds of our hill stations. It is a reddish brown fowl, about eight inches long. Each of its feathers has a black shaft; it is these dark shafts that give the bird its streaked appearance. Its chin, throat, and breast are chestnut-red, and on each cheek there is a patch of similar hue. The general appearance of the streaked laughing-thrush is that of one of the seven sisters who is wearing her best frock. Like their sisters of the plains, Himalayan streaked laughing-thrushes go about in small flocks and are exceedingly noisy. Sometimes a number of them assemble, apparently for the sole purpose of holding a speaking competition. They are never so happy as when thus engaged. Streaked laughing-thrushes frequent gardens, and, as they are inordinately fond of hearing their own voices, it is certainly not their fault if they escape observation. By way of a nest they build a rough-and-ready cup-shaped structure in a low bush or on the ground; but, as Hume remarked, "the bird, as a rule, conceals the nest so well that, though a loose, and for the size of the architect, a large structure, it is difficult to find, even when one closely examines the bush in which it is." Three other species of laughing-thrush must be numbered among common birds of the Himalayas, although they, like the heroine of _A Bad Girl's Diary_, are often heard and not seen. The white-throated laughing-thrush (_Garrulax albigularis_) is a handsome bird larger than a myna. Its general colour is rich olive brown. It has a black eyebrow and shows a fine expanse of white shirt front. It goes about in large flocks and continually utters a cry, loud and plaintive and not in the least like laughter. The remaining laughing-thrushes are known as the rufous-chinned (_Ianthocincla rufigularis_) and the red-headed (_Trochalopterum erythrocephalum_). The former may be distinguished from the white-throated species by the fact that the lower part only of its throat is white, the chin being red. The red-headed laughing-thrush has no white at all in the under parts. The next member of the family of the Crateropodidae that demands our attention is the rusty-cheeked scimitar-babbler (_Pomatorhinus erythrogenys_). Scimitar-babblers are so called because of the long, slender, compressed beak, which is curved downwards like that of a sunbird.
