Location of the Falkland Islands

The Falkland Islands wolf (Dusicyon australis), also known as the warrah (/ˈwɑːrə/ WAH-rə or /ˈwɑːrɑː/ WAH-rah) and occasionally as the Falkland Islands dog, Falkland Islands fox, warrah fox, or Antarctic wolf, was the only native land mammal of the Falkland Islands.[3] This endemic canid became extinct in 1876, the first known canid to have become extinct in historical times.

Traditionally, it had been supposed that the most closely related genus was Lycalopex, including the culpeo, which has been introduced to the Falkland Islands in modern times. A 2009 cladistic analysis of DNA identified the Falkland Islands wolf's closest living relative as the maned wolf (Chrysocyon brachyurus), an unusually long-legged, fox-like South American canid, from which it separated about 6.7 million years ago.[4] However, the Falkland Islands wolf diverged from its mainland ancestor Dusicyon avus very recently, around 16,000 years ago.[5] Dusicyon avus persisted on the South American mainland until around 400 years ago.[6]

The Falkland Islands wolf existed on both West and East Falkland, but Charles Darwin was uncertain if they were differentiated varieties or subspecies.[7] Its fur had a tawny colour and the tip of the tail was white. Its diet is unknown, but due to the absence of native rodents on the Falklands, probably consisted of ground-nesting birds, such as geese and penguins, seal pups and insects, as well as seashore scavenging.[8] It has sometimes been said that it may have lived in burrows.[9]
