The Caspian plover is a slim, upright bird with long, thin legs which allow it to wade in shallow water, and a black, narrow, pointed bill. The plumage of the Caspian plover varies between the sexes. The male has a brilliant white forehead, throat and underparts, which stand out against the sandy-brown upper body and tail, and a rusty red breast which is bordered by a narrow, black band. The female, on the other hand, has a greyish, yellow breast and lacks the black breast band. During the winter months the plumage of both the males and the females becomes darker, as many of the white feathers are replaced by sandy-brown feathers. The plumage of the juvenile Caspian plover largely resembles the adults’ winter plumage, apart from a few of the wing feathers which have flashes of yellow around the edges. The Caspian plover is often silent, but can give a clear, whistling call.
