Mountain hare  (Lepus timidus)

The mountain hare, also known as the blue hare, or white hare in winter, is native to Britain, unlike the brown hare (Lepus europaeus) and rabbit (Oryctolagus cuniculus), which are thought to have been introduced by the Romans (4). It has a lighter build than the brown hare, and is easily distinguished by its tail, which is completely white throughout the year, whereas in the brown hare the tail has a black upper surface (2). The ears are tipped with black, and the coat is brown in summer, turning white during winter (4). Males and females are generally similar in appearance, but females are slightly heavier (4).
