''Syrrhaptes'' is a genus of birds in the sandgrouse family. It comprises two central Asian species. * Tibetan sandgrouse, ''Syrrhaptes tibetanus'' * Pallas's sandgrouse, ''Syrrhaptes paradoxus'' These are large birds breeding in open steppes or plateau. They nest in a ground scrape into which three eggs are laid. Both species have mainly buff upperparts, an orange face and feathered legs and toes. They are smaller-headed than other sandgrouse, but have sturdy compact bodies. Although there is range overlap, they are easily distinguished. Tibetan sandgrouse has a white belly and black underwings, whereas Pallas's has a black belly and white underwings. These birds are gregarious like other sandgrouse. Flocks fly to watering holes at dawn and dusk, on long pointed wings. ==References== * ''Pheasants, Partridges and Grouse'' by Madge and McGowan, ISBN 0-7136-3966-0 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Syrrhaptes」の詳細全文を読む スポンサード リンク
