Brown Hares are thought to have been introduced to the UK in Roman or earlier times. They have become a firm favourite with many people hence their frequent appearance on greetings cards and in wildlife pictures. They differ from rabbits in a number of ways, and as well as being larger are easily distinguished in the field by their longer ears with black tips, and also by the black marking on their white tail. Hares live in open farmland and rather than creating burrows like rabbits do, they use depressions in the ground, called "forms". As you can see in some of the photographs they have powerful long back legs which help them travel at speed, especially uphill, which gives them an advantage when chased by predators.
