The European rabbit or common rabbit (Oryctolagus cuniculus) is a species of rabbit native to southwestern Europe (Spain and Portugal) and northwest Africa (Morocco and Algeria).[3] It has been widely introduced elsewhere, often with devastating effects on local biodiversity. However, its decline in its native range (caused by the diseases myxomatosis and rabbit calicivirus, as well as overhunting and habitat loss), has caused the decline of its highly dependent predators, the Iberian lynx and the Spanish imperial eagle. It is known as an invasive species because it has been introduced to countries on all continents with the exception of Antarctica and sub-Saharan Africa, and caused many problems within the environment and ecosystems. Australia has the most problems with European rabbits, due to the lack of natural predators there.
The European rabbit is well known for digging networks of burrows, called warrens, where it spends most of its time when not feeding. Unlike the related hares (Lepus spp.), rabbits are altricial, the young being born blind and furless, in a fur-lined nest in the warren, and they are totally dependent upon their mother. Much of the modern research into wild rabbit behaviour was carried out in the 1960s by two research centres. One was the naturalist Ronald Lockley, who maintained a number of large enclosures for wild rabbit colonies, with observation facilities, in Orielton, Pembrokeshire. Apart from publishing a number of scientific papers, he popularised his finding in a book The Private Life of the Rabbit,[4] which is credited by Richard Adams as having played a key role in his gaining "a knowledge of rabbits and their ways" that was espoused in the novel Watership Down. The other group was the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia, where Mykytowycz and Myers performed numerous studies of the social behaviour of wild rabbits. Since the onset of myxomatosis, and the decline of the significance of the rabbit as an agricultural pest, few large-scale studies have been performed and many aspects of rabbit behaviour are still poorly understood.
Terminology
Rabbits are known by many names. Young rabbits are known by the names 'bunny', 'kit', or 'kitten'. A male rabbit is called a 'buck', and a female rabbit is called a 'doe'. A group of rabbits is known as a 'colony' or a 'nest'.[5] Colloquially, a rabbit may be referred to as a "coney" or a "bunny", though the former is archaic.

The European rabbit is a smallish, grey-brown (or sometimes black) mammal, although it ranks as medium-sized by lagomorph standards. It ranges from 34 to 50 cm (13 to 20 inches) in length, not counting a tail of 4 to 8 cm (1.6 to 3.1 in). Weight can range from approximately 1.1 to 2.5 kg (2.4 to 5.5 lb).[6] As a lagomorph, it has four sharp incisors (two on top, two on bottom) that grow continuously throughout its life, and two peg teeth on the top behind the incisors, dissimilar to those of rodents (which have only two each, top and bottom). Rabbits have long ears, large hind legs, and short, fluffy tails. Rabbits move by hopping, using their long and powerful hind legs. To facilitate quick movement, a rabbit's hind feet have a thick padding of fur to dampen the shock of rapid hopping. Their toes are long, and are webbed to keep from spreading apart as the animal jumps.
Ecology and behavior
Habitat
European rabbits typically spend much of their time grazing on grass.
Rabbits are social animals, living in medium-sized colonies known as warrens. They are largely crepuscular, being most active around dawn and dusk, although they are not infrequently seen active during the day. During the day, rabbits prefer to reside in vegetated patches, which they use for protection from predators.[7] At night, they move into open prairie to feed.[7] Rabbit populations seem to be greatest in
