Medium-sized plover with a long hefty bill. Breeding adults have a dark mask and orangish chest, neck, and forehead; females duller than males. Non-breeding birds and immatures are sandy brown above and white below, with a white throat and “eyebrows.” Often confused with Lesser Sand-Plover, and best distinguished when both present; look for larger size, heavier and longer bill, paler legs, and larger-headed appearance. Additionally, unlike some Lesser Sand-Plovers, Greater never has a black boundary around the throat. Breeds in high-elevation areas, where it favors arid, open habitats, sometimes near water. Winters on coastal mudflats and estuaries.
