Pallas's sandgrouse (Syrrhaptes paradoxus) is a medium large bird in the sandgrouse family named after the German zoologist Peter Simon Pallas. The scientific name is from Ancient Greek. The genus Syrrhaptes is from surrhaptos, 'sewn together' (the feathered toes of both species in the genus are fused together) and paradoxus is from paradoxos, 'strange'. [2]
Pallas's sandgrouse is 30–41 cm (12–16 in) long with small, pigeon-like head and neck, but sturdy compact body. It has long pointed wings and tail and legs and toes are feathered. Its plumage is buff coloured, barred above with a black belly patch and pale underwings. The black belly and pale underwing distinguish this species from the related Tibetan sandgrouse. The male Pallas's sandgrouse is distinguished by its grey head and breast, orange face and grey breast band. The female has duller plumage and lacks the breast band though it has more barring on the upperparts.
The small feet lack a hind toe, and the three front toes are fused together. The upper surface is feathered, and the underneath has a fleshy pad. The appearance of the foot is more like a paw than an avian foot. [3]
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.
Pallas's sandgrouse occasionally irrupts 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.
Due to their primarily dry diet of seeds, the sandgrouse needs to drink a large volume of water. The sandgrouse's wing morphology allows for fast flight with speeds up to 64 km/h (40 mph) having been recorded. Large flocks of several thousand individuals fly to watering holes at dawn and dusk making round trips of up to 121 km (75 mi) per day. [4] Male parents soak their breast plumage in water while drinking, allowing their chicks to drink from the absorbed moisture on their return. [5]
Marco Polo mentions a bird called Bargherlac (from Turkmen bağırlak) in The Travels of Marco Polo. This is probably Syrrhaptes paradoxus (S. pallasii). [6]
The isabelline wheatear is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher in the family Muscicapidae. It is a migratory insectivorous bird. Its habitat is steppe and open countryside and it breeds in southern Russia and Central Asia to northern Pakistan, wintering in Africa and northwestern India. It is a very rare vagrant to western Europe.
The desert wheatear is a wheatear, a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but is now more generally considered to be an Old World flycatcher (Muscicapidae). It is a migratory insectivorous species, 14.5 to 15 cm in length. Both western and eastern forms of the desert wheatear are rare vagrants to western Europe. The western desert wheatear breeds in the Sahara and the northern Arabian peninsula. The eastern race is found in the semi-deserts of Central Asia and in winter in Pakistan and northeast Africa.
Sandgrouse is the common name for Pteroclidae, a family of sixteen species of bird, members of the order Pterocliformes. They are traditionally placed in two genera. The two central Asian species are classified as Syrrhaptes and the other fourteen species, from Africa and Asia, are placed in the genus Pterocles. They are ground dwelling birds restricted to treeless, open country, such as plains, savannahs, and semi-deserts. They are distributed across northern, southern, and eastern Africa, Madagascar, the Middle East, and India through central Asia. The ranges of the black-bellied sandgrouse and the pin-tailed sandgrouse even extend into the Iberian Peninsula and France, and Pallas's sandgrouse occasionally breaks out in large numbers from its normal range in Asia.
The pin-tailed sandgrouse is a medium large bird in the sandgrouse family. It has a small, pigeon like head and neck and a sturdy, compact body. It has long pointed wings, which are white underneath, a long tail and a fast direct flight. Flocks fly to watering holes at dawn. The call is a loud kattar-kattar. This gregarious species breeds on dry open treeless plains and similar habitats. Its nest is a ground scrape into which two or three cream-coloured eggs with cryptic markings are laid. Both sexes incubate the eggs.
The black-bellied sandgrouse is a medium large bird in the sandgrouse family.
The Tibetan sandgrouse is a large bird in the sandgrouse family. The genus name Syrrhaptes is from Ancient Greek surrhaptos, "sewn together" and tibetanus is from the type locality, Tibet.
Syrrhaptes is a genus of birds in the sandgrouse family. The genus name is from Ancient Greek surrhaptos, "sewn together"; the feathered toes of birds in this genus are fused together.
Pterocles is a genus of near passerine birds in the sandgrouse family. It includes all the species in the family except for two central Asian species in Syrrhaptes
The chestnut-bellied sandgrouse or common sandgrouse is a species of sandgrouse. It is a sedentary and nomadic species that ranges from northern and central Africa and further east towards western and southern Asia. There are six recognised subspecies.
The crowned sandgrouse is a species of bird in the sandgrouse family, the Pteroclidae from North Africa and the Middle East.
The Madagascar sandgrouse is a species of bird in the family Pteroclidae. It is endemic to Madagascar and is a ground-dwelling short-legged plump bird. The head of the male is brown with a black area surrounding the beak. It has a pinkish-buff coloured breast, a light brown mottled back, brown wings and paler underparts barred with dark brown. The female has a generally duller appearance being cryptically coloured brown with dark specks and bars.
The spotted sandgrouse is a species of ground dwelling bird in the family Pteroclidae. 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.
The forest buzzard, is a species of bird of prey found in Africa, though some authorities have placed it as a subspecies of another species, the mountain buzzard, Buto oreophilus. This is a resident breeding species in woodlands in southern and eastern South Africa.
