This species breeds across middle latitudes of central Asia on dry steppes and similar habitats. Its nest is a ground scrape into which 2-3 greenish eggs with cryptic markings are laid. It is a partial migrant, especially from the northern parts of its range in Kazakhstan and Mongolia, but the extent and distance of the southerly winter movement depends on the amount of snowfall. The steppe of Western Kazakhstan in early spring In physical geography, steppe (from Slavic step) is a plain without trees (apart from those near rivers and lakes); it is similar to a prairie, although a prairie is generally reckoned as being dominated by tall grasses, while short grasses are said... Long-distance land bird migration Many species of land birds migrate very long distances, the most common pattern being for birds to breed in the temperate or arctic northern hemisphere and winter in warmer regions, often in the tropics or the southern hemisphere. ...

Pallas's Sandgrouse occasionally erupts from its regular breeding and wintering range across Europe as far west as Great Britain, where it has bred, and Ireland. The reasons for these remarkable movements are not fully understood, but they have become less frequent, probably due to contraction of the western Siberian range as the steppes become more agricultural.

Pallas's Sandgrouse is 30-41cm long, with buff plumage, barred above, a black belly patch and pale underwings. The male has a grey head and breast, orange face and grey breast band. The female lacks the breast band, has more barring on the upperparts and is duller.

The black belly and pale underwing distinguish this species from the related Tibetan Sandgrouse. Binomial name Syrrhaptes tibetanus (Gould, 1850) The Tibetan Sandgrouse (Syrrhaptes tibetanus ) is a large bird in the sandgrouse family. ...

This sandgrouse has a small, pigeon-like head and neck, but sturdy compact body. It has long pointed wings and tail and a fast direct flight. Flocks fly to watering holes at dawn and dusk. The legs and toes are feathered.

This bird is named after the German zoologist Peter Simon Pallas. Peter Simon Pallas (September 22, 1741 - September 8, 1811) was a German-born Russian zoologist. ...
