Mountain hare (Lepus timidus)

About the Mountain hare

The Mountain Hare (Lepus timidus), also known as Blue Hare, Tundra Hare, Variable Hare, White Hare, Alpine Hare and Irish Hare, is a hare, which is largely adapted to polar and mountainous habitats. It is distributed from Fennoscandia to eastern Siberia; in addition there are isolated populations in the Alps, Ireland, Poland, the United Kingdom and Hokkaidō. It has also been introduced to Shetland and the Faroe Islands.

In Summer, for all populations of mountain hares, the coat is various shades of brown. In preparation for winter most populations moult into a white (or largely white) pelage. The subspecies Irish Mountain Hare (Lepus timidus hibernicus) stays brown all year and only rarely do individuals develop a white coat. The Irish race may also have a dark/grey upper surface to the tail, which in other populations always remains white. This tail color combined with its large size (in comparison to most other populations of mountain hare) and the various shades of brown that the Irish hare may display, could lead an unexperienced observer to misidentifying an Irish mountain hare as a brown hare (Lepus europaeus).

Studies have shown that the diet of the mountain hare varies from region to region. It seems to be somewhat dependent on the particular habitat that the population under study lives in. For example, in northern Scandinavia where snow may blanket the ground for many months, the hares may graze on twigs and bark. In areas where snowfall is rare, such as Ireland, grass may form the bulk of the diet. Given a choice, mountain hares (in Scotland and Ireland at least)seem to prefer feeding on grasses. One study looking at mountain hares on a coastal grassland environment in Ireland found that grasses constituted over 90% of the diet. This was higher than the percentage of grass in the diet of rabbits (Oryctolagus cuniculus) that inhabited the same environment.

The Mountain Hare is the provincial animal of Medelpad in Sweden.

In northern parts of Finland and Sweden, the Mountain Hare and the European Hare compete for habitat. The European Hare, being larger, is usually able to drive away the Mountain Hare but is less adapted for living in snowy regions: its feet are smaller and its winter fur is a mixture of white and brown. While this winter fur is actually a very good camouflage in the coastal regions of Finland where the snow covers the shrubs but for a short time, the Mountain Hare is better adapted for the snowier conditions of the inland areas.

The Arctic Hare (Lepus arcticus) was once considered a subspecies of the Mountain Hare, but it is now regarded as a separate species. Similarly, some scientists believe that the Irish Hare should be regarded as a separate species.
