STONE-CHATTERER, (Motacilla Rubicola), in ornithology, a species omitted to be described under MOTACILLA. It is common among us during summer in gorgy grounds. In the winter they disperse into marshes and other places, but do not quit the island. It is a restless and noisy bird, and perches frequently on some bush, chattering incessantly. The head, neck, and throat, are black; but on both sides of the latter is a white bar, so that it appears on first sight to be encircled with white: the feathers on the back are black, edged with tawny; the lower part of the back just above the rump is white: the end and exterior side of the two outmost feathers of the tail are of a pale rust-colour, the rest are black: the breast is of a deep reddish yellow; the belly of a lighter hue: the quill-feathers are dusky edged with dull red; those next the body are marked with a white spot near their bottoms; the coverts of the wings are adorned with another. The head of the female is ferruginous spotted with black; and the colours in general are less vivid. In both sexes the legs are black.
