Carcass Island is a privately owned island of about 19 km² off the north-west tip of West Falkland, named after HMS Carcass, which called in 1766. It has been a sheep farm for more than a century, and its owners have kept it free of rats, mice and cats.
As a result its birdlife is unusually tame and abundant, including the endemic Cobb's wren, tussacbirds, long-tailed meadowlarks and the rare striated caracara, or 'Johnny Rook'. Gentoo and Magellanic penguins breed above the white-sand beaches, elephant seals haul out at the northern end, and the island is recognized as an Important Bird Area.
The small settlement at Port Pattison sits on a sheltered harbor with planted trees and gardens. Carcass is a regular stop on expedition cruises to the Falklands, South Georgia and Antarctica, and visits often end with tea and home-made cakes at the farmhouse.
