Giant Killer Mice of Gough Island
In regard to biology, Gough is best known for its “giant killer mice.” Inadvertently introduced house mice have evolved into a new form roughly three times the size of their progenitors. Unfortunately, these super-rodents have learned to prey on seabird nestlings. In 2005, researchers announced that mice predation risked driving several endemic bird species to extinction, including the Tristan albatross and the Atlantic petrel. In response, the British government brought in experts from New Zealand, who have considerable experience dealing with biologically threatened islands. Officials in Britain are currently considering their proposals for eliminating the killer mice.
