Adult male Watercocks are 43 cm long. They have mainly black-grey plumage with red legs, bill, forehead shield and horn. Young males are buff in colour, darkening as they mature. Their bill is yellow and their legs are green.
Female birds are smaller at 36 cm, and are dark brown above and paler below. the plumage is streaked and barred with darker markings. The bill is yellow and the legs are green. The downy chicks are black, as with all rails.
These birds probe with their bill in mud or shallow water, also picking up food by sight. They mainly eat insects and small fish and seeds. They forage on the ground.
Watercock are quite secretive, but are sometimes seen out in the open. They are noisy birds, especially at dawn and dusk, with a loud, gulping call.
