Note 21 — THE ASIATIC STEPPES AND THEIR FAUNA.
Margaret R. Thomson translation
[Note 21] p. 106.—Sand-grouse.
Sand-grouse (Pterocles and Syrrhaptes), a group of birds quite distinct from the grouse. One species, Syrrhaptes paradoxus, “ranging from Northern China across Central Asia to the confines of Europe”, has shown a tendency to extensive migration, visiting Britain, for instance, in 1859, 1863, 1872, 1876, and abundantly in 1888. For a concise account of these irregular invasions see Newton’s Dictionary of Birds.
