Pallas's sandgrouse (Syrrhaptes paradoxus) is a medium large bird in the sandgrouse family named after the German zoologist Peter Simon Pallas.
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.
