Informations supplémentaires:
It lies north-west of West Falkland and south-east of the Jason Islands. It is 10 km (6.2 mi) in length, has a maximum width of 2.5 km (1.6 mi), and is 19 km2 (7.3 sq mi) in area.[1] The highest points of the island are Stanley Hill and Mount Byng at 220 m (720 ft). The north-eastern coast has cliffs and slopes while there are large sand bays and a tidal rocky point to the north-west. There are also stretches of duneland. Leopard Beach is often used as a landing point. The island's grim-sounding name comes from the ship HMS Carcass, which surveyed the island in 1766. Its accompanying vessel, HMS Jason, gave its name to the nearby Jason Islands, and its captain, John McBride, gave his name to MacBride Head. The duck has a grey chin, neck and face, with the body plumage a mixture of brown and grey feathers giving a mottled look. Its eyes are red with black pupils. The crown and the feathers surrounding the eyes are dark brown or blackish. The tail feathers are also dark, sometimes black. It has a black beak and dark grey to black legs and webbed feet. It moults twice a year and also has an annual wing feather moult. It is a medium-sized duck around 50–60 cm in length. Females and males weigh about 1 kg though usually the males are slightly larger. It is very similar to the other subspecies, the Andean crested duck, differing in being slightly smaller, with more distinctively mottled underparts, and a lighter purple speculum with green or bronze reflections. Young ducks have smaller crests than the adults, or lack crests entirely. The faces of the young birds are browner than those of the adults; the abdomen is also much whiter and the mandible a pinkish colour
