Hares and jackrabbits are mammals belonging to the genus Lepus. They are herbivores, and live solitarily or in pairs. They nest in slight depressions called forms, and their young are able to fend for themselves shortly after birth. The genus includes the largest lagomorphs. Most are fast runners with long, powerful hind legs, and large ears to dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a 'leveret'. A group of hares is called a 'husk', a 'down' or a 'drove'. Hares and rabbits are plentiful in many areas, adapt to a wide variety of conditions, and reproduce quickly, so hunting is often less regulated than for other varieties of game. In rural areas of North America and particularly in pioneer times, they were a common source of meat. Because of their extremely low fat content, they are a poor choice as a survival food.
