The LARGE PIN-TAILED GROUSE, or KHATA (_Pterocles alchata_), is somewhat smaller than the Ganga, and has the feathers more highly coloured. Like that bird, the plumage is principally of a sandy yellow, the brow and sides of the cheeks being reddish brown, the throat and a delicate line commencing at the eye and passing to the back of the head are black; the nape and the back brownish-greyish green, spotted with yellow; the small wing-covers greyish crimson, their upper feathers striped with reddish brown, then with light yellow, and again with deep brown; the feathers of the larger covers are greyish-greenish yellow, bordered with blackish brown; the lower part of the throat is reddish fawn-colour; the upper breast bright crimson-brown, surrounded above and below by a narrow black line, and the belly white. The quills are grey, with black shafts shading beneath to a deeper tint; the shoulder-feathers are greenish grey above and fawn-grey on the lower surface; most of the tail-feathers are striped grey and yellow on the outer, and grey tipped with white on the inner web; while the long centre pair are greenish grey, marked with faint stripes. The plumage of the female resembles that of her mate, but is readily distinguished by the stripes upon her mantle, a double line upon her throat, enclosing a patch of greyish yellow, and by the white hue of its upper portion. The eye is brown, the beak dark grey, and the foot of a brownish shade. The length of the male is twelve inches and three-quarters, the breadth twenty-two inches and a half; the wing measures seven inches, and the tail five inches. This well-known Sand Grouse inhabits Northern Africa, Western Asia, and the south of Europe, especially Spain, Sicily, and the Levant, and it occasionally penetrates through Central Asia to the Punjaub and Scinde. "The Khata," says Jerdon, "is a comparatively rare bird in India, only a few finding their way across the Sutlej. I presume that, like _P. arenarius_, it is migratory to this country, and only found in the cold season." It is a very beautiful bird, and the bill is thicker and stronger than that of any other of the genus.
