The LITTLE BUSTARD (_Otis tetrax_, or _Tetrax campestris_) differs from the above species, not only in the inferiority of its size and general coloration, but in the curious prolongation of the feathers on the nape and throat. In the male bird the black throat is enlivened by white streaks, one of which passes from the ear to the gullet, and the other over the crop; the face is dark grey, the top of the head light yellow spotted and marked with black; the edges of the wings, feathers of the tail-covers and entire under side are white, the quills dark brown, and tail-feathers white, marked with two lines at their extremity. The eye is light or brownish, the beak horn-grey tipped with black, and the foot straw-colour. The length of this species is from eighteen to nineteen inches, its breadth thirty-six inches, the wing measures ten and the tail five inches. The female is smaller than her mate, and has the side of her head of a yellowish hue; her throat is whitish; breast light yellow, striped with black; the spots upon her mantle are more clearly defined than in the plumage of the male; the feathers of her upper wing-covers are white spotted with black; her under side is white. The Little Bustard is met with principally in the southern parts of Europe, extending from the south of France, over Turkey, Greece, Italy, and Spain; it is particularly numerous in Sardinia, and is seen in large flocks upon the steppes of Southern Russia, particularly during the migratory season. According to Yarrell, this bird can only be regarded as an accidental or winter visitor to Great Britain, it having been killed here only between autumn and the middle of spring. The nest or eggs have never been found in the British Islands. In the course of its migrations, it occasionally visits the country round the Altai Mountains, and Syria. During our stay in Egypt, we saw but a single specimen. Unlike the larger species, the Little Bustard is not restricted to flat and open districts, but frequently inhabits mountainous regions; in Spain it principally occupies vineyards, wherever these may be situated. Although closely resembling the species last described in many respects, it yet differs from it considerably in the ease and comparative lightness of its movements. Its gait is more graceful, and its pace extraordinarily rapid; its flight is swift and capable of being long-sustained. In disposition it is cautious, but by no means so shy as the Great Bustard: if disturbed it seeks safety by squatting close to the ground among the grass or brushwood; and its voice is seldom heard except during the period of incubation. Insects, worms, beetles, grasshoppers, larvæ, and occasionally portions of plants or seeds constitute the food of this species; the young probably are reared exclusively on insect diet. The breeding season commences about the end of April, and is inaugurated by violent battles between the male birds;
