The European rabbit is smaller than the European hare and Mountain hare and lacks black ear tips, as well as having proportionately shorter legs. The fur of the European rabbit is generally greyish-brown, but this is subject to much variation. The guard hairs are banded brown and black, or grey, while the nape of the neck and scrotum are reddish. The chest patch is brown, while the rest of the underparts are white or grey. A white star shape is often present on kits' foreheads but rarely occurs in adults. The whiskers are long and black, and the feet are fully furred and buff-coloured. The tail has a white underside, which becomes prominent when escaping danger. This may act as a signal for other rabbits to run. Moulting occurs once a year, beginning in March on the face and spreading over the back. The underfur is completely replaced by October-November. The European rabbit exhibits great variation in colour, from light sandy to dark grey and completely black. Such variation depends largely on the amount of guard hairs relative to regular pelage.
European rabbits are found in southwestern Europe (including Portugal, Spain, and western France) and in northwest Africa (including Morocco and Algeria). Their ideal habitat consists of short grasslands with secure refuge (such as burrows, boulders, hedgerows, scrub, and woodland) near feeding areas. In large coniferous plantations, European rabbits only occur in peripheral areas and along fire breaks and rides.
European rabbits are herbivores (graminivores) and coprophages. They eat a wide variety of herbage, especially grasses, favoring the young, succulent leaves and shoots of the most nutritious species. Hungry rabbits in winter may eat tree bark and blackberries. Like other leporids, European rabbits also consume their own fecal pellets, which are filled with protein-rich bacteria.
European rabbits exhibit an interesting mating system; dominant bucks are polygynous, whereas lower-status individuals (both bucks and does) often form monogamous pairs. Rabbits signal their readiness to mate by marking other animals and inanimate objects with an odoriferous substance secreted through a chin gland; this process is known as "chinning". The breeding season usually takes place from January to August. Does give birth to 3-7 kittens after the gestation period of 30 days. Shortly before giving birth, the doe will construct a separate burrow known as a "stop" or "stab", generally in an open field away from the main warren. These breeding burrows are typically a few feet long and are lined with grass and moss as well as fur plucked from the doe's belly. The breeding burrow protects the kittens from adult bucks as well as from predators. Kittens are altricial, being born blind, deaf, and furless, and they are totally dependent upon their mother. The young born to the dominant buck and doe enjoy better nesting and feeding grounds; they tend to grow larger and stronger and become more dominant than kittens born to subordinate rabbits. Does nurse their kittens once a night, for only a few minutes. After suckling is complete, the doe seals the entrance to the stop with soil and vegetation. The kittens grow rapidly and their eyes open 11 days after birth. The ears do not gain the power of motion until 10 days of age and can be erected after 13. At 18 days, the kittens begin to leave the burrow and at 4 weeks they are weaned. Young bucks become reproductively mature at four months of age, while does can begin to breed at three to five months.
