Hares and jackrabbits are leporids belonging to the genus Lepus. Hares are classified in the same family as rabbits. They are similar in size to rabbits and have similar herbivorous diets, but generally have longer ears and live solitarily or in pairs. They do not dig burrows but nest in slight depressions called 'forms', often in long grass. Also unlike rabbits, their young are able to fend for themselves shortly after birth rather than emerging blind and helpless. Most are fast runners. Hare species are native to Africa, Eurasia and North America.
