Red fox

The red fox (Vulpes vulpes) is the largest of the true foxes, and the most widely distributed member of the order Carnivora. It is present across the entire Northern Hemisphere, including most of North America, Europe and Asia, as well as parts of North Africa. Its range has expanded alongside human settlement, with the species having been introduced to Australia, where it preys on native small and medium-sized rodents and marsupials. The red fox is listed as of least concern on the IUCN Red List. Because of its impact on native species, it is included on the list of the "world's 100 worst invasive species". The red fox originated in Eurasia during the Middle Pleistocene at least 400,000 years ago and later colonised North America sometime prior to 130,000 years ago. Apart from its large size, the red fox is distinguished from other fox species by its ability to adapt quickly to new environments. Despite its name, the species often produces individuals with other colourings, including leucistic and melanistic individuals. Forty-five subspecies are currently recognised, which can be divided into two categories: the large northern foxes and the small, basal southern grey desert foxes of Asia and North Africa. The red fox usually occurs in pairs or in small family groups consisting of a mated pair and their young, or a male with several females related to each other. The young of the mated pair stay with their parents to help care for the new kits. The red fox primarily feeds on small rodents, though it also hunts rabbits, squirrels, game birds, reptiles, invertebrates and young ungulates. It also eats fruit and vegetables. Although it tends to kill smaller predators, including other fox species, it is vulnerable to attack from predators, such as the golden eagle, Eurasian goshawk, Bonelli's eagle,...
