On 18 March last year a fox, or foxes, found their way through a damaged fence into the penguin enclosure at London Zoo and slaughtered 11 rockhopper and blackfooted penguins. News of the massacre only appeared this weekend, after the Independent got hold of a report on the zoo from inspectors at Westminster Council; since 2007, foxes have also killed a flamingo chick, a chicken and two mara (which the Independent described as ‘rodents resembling small kangaroos’; they’re more like guinea pigs on stilts).
