=The Sand Grouse.=--Pallas’s sand grouse is a native of the Kirghiz steppes of central Asia, and occasionally, driven by some pressure of circumstances of which we can only conjecture the nature, makes visits to England. Its presence in that country has never been recorded till this century--more, perhaps, for lack of observers than of migrating birds--but it has appeared in 1863, 1872, 1873, 1888, 1889, and 1899. The principal migration in recent years was in 1888, when many examples were seen and shot in different parts of the country. In the same year it was seen “far and wide” in western Europe, and as far north as Trondhjem, in western Norway. A writer in the Saturday Review remarks on the resemblance of this sand grouse, as described by Prjevalski in central Asia, to the various sand grouse he has seen in South Africa. At the drinking places they circle round the water. Presently they alight and, Prjevalski says, “hastily drink and rise again, and, in cases where the flocks are large, the birds in front get up before those at the back have time to alight. They know their drinking places very well, and very often go to them from distances of tens of miles, especially in the mornings, between nine and ten o’clock, but after twelve at noon they seldom visit these spots.” In the Kalahari country, at the scant desert waters, the Saturday Review writer says, three kinds of sand grouse “are to be seen flocking in from all parts of the country from eight to ten o’clock A. M. for their day’s drink. Circling swiftly round the pool with sharp cries, they suddenly stoop together toward the water. The noisy rustle of their wings as they alight and ascend is most remarkable. We noticed that the birds nearest the water drank quickly and moved off, allowing those in the rear to take their places and slake their thirst, the whole process being accomplished with unfailing order and regularity.... The spectacle of these punctual creatures, streaming in from all points of the compass with unfailing regularity between eight and ten o’clock was always most fascinating. After drinking they circled once or twice round the water pool, and then flew off with amazing swiftness for their day of feeding in the dry, sun-scorched desert. The seeds of grass and other desert plants seem to constitute their principal food. The sand grouse has some characteristics of the pigeon and some of the grouse, which suggest a ‘singular blending’ of the two orders.” * * * * *
