The spotted sandgrouse (''Pterocles senegallus'') is a species of ground dwelling bird in the Pteroclididae family. It is found in arid regions of northern and eastern Africa and across the Middle East and parts of Asia as far east as northwest India. It is a gregarious, diurnal bird and small flocks forage for seed and other vegetable matter on the ground, flying once a day to a waterhole for water. In the breeding season pairs nest apart from one another, the eggs being laid in a depression on the stony ground. The chicks leave the nest soon after hatching and eat dry seed, the water they need being provided by the male which saturates its belly feathers with water at the waterhole. The spotted sandgrouse is listed as being of "least concern" by the International Union for Conservation of Nature in its Red List of Threatened Species. ==Description== The spotted sandgrouse reaches a length of about . The male has a small reddish-brown nape surrounded by a band of pale grey that extends to the bill and round the neck in a collar. The chin, neck and throat are orange and the breast grey. The upper parts are pinkish-grey with dark flight feathers and dark patches on the wings, tail and lower belly. The primaries are pale with dark trailing edges, a fact that distinguishes this species from the crowned sandgrouse (''Pterocles coronatus'') which has completely dark primaries. The female also has an orange throat region but is generally duller in plumage than the male. The body colour is greyish-brown liberally spotted with small dark markings and with dark patches on the wings, tail and lower belly. The central tail feathers in both sexes are elongated but not to the extent that they are in the pin-tailed sandgrouse (''Pterocles alchata''). When flying overhead, a dark belly stripe is visible.
