What is a hare?
A hare is a mammal belonging to the genus Lepus of the family Leporidae, related to rabbits. Hares typically have longer ears and hind feet compared to rabbits. They are herbivorous animals with powerful hind legs, short tails, and long ears.
Hares are the largest lagomorphs, with body lengths ranging from about 40 to 70 cm. While usually gray-brown, some hares that live in northern latitudes turn white in winter. Hares are widespread, found throughout North America, Europe, Asia, and Africa.

How is a hare different from a rabbit?
Hares and rabbits, both mammals in the family Leporidae, are often mistaken for each other. Despite their similarities, key differences exist. Hares are generally larger than rabbits, with longer ears and hind legs.
Rabbits are born without fur and with closed eyes after a gestation period of 30 to 31 days. They prefer habitats with trees and shrubs, living in burrows. Hares, however, are born fully developed with fur and open eyes following a gestation of about 42 days. They favor open areas like prairies, nesting in small depressions.

Where do hares usually live?
Hares are widespread, inhabiting North America, Europe, Asia, and Africa. They favor open areas like prairies, where they create nests in shallow, open depressions, but some live in the far north, such as the Arctic hare and snowshoe hare.
Unlike rabbits, who prefer habitats of trees and shrubs and hide from their enemies, hares rely on running and live in open areas.

How do hares protect themselves from predators?
Hares use several strategies to protect themselves from predators. As runners, they prefer open areas like prairies, where they nest in small, open depressions. When threatened, hares rely on rapid locomotion to escape. They may also display conspicuous behaviors during escape, such as showing colored hind wings, to make it difficult for predators to track their movements.
Camouflage also helps hares avoid predators. Their typically gray-brown color helps them blend into their surroundings. Some hares, like those in northern latitudes, turn white in winter to match the snowy environment.

Why are hares important in their ecosystems?
Hares play a crucial role in their ecosystems as a food source for various carnivorous birds, mammals, and reptiles. They are almost exclusively herbivorous, and when their populations are high, they can significantly impact natural vegetation or crops.
One notable ecological pattern is the boom-and-bust cycle of snowshoe hare populations in North American boreal forests, peaking every 8–11 years before sharply declining. This cycle influences predator populations like the Canada lynx, whose density increases with the hare population, followed by a crash when hare numbers decline.

hare, (genus Lepus), any of about 30 species of mammals related to rabbits and belonging to the same family (Leporidae). In general, hares have longer ears and longer hind feet than rabbits. While the tail is relatively short, it is longer than that of rabbits. The vernacular names hare and rabbit are frequently misapplied to particular species. Jackrabbits of North America, for example, are actually hares, while the hispid hare (Caprolagus hispidus) of Nepal and India is a rabbit, and the mouse hare is another name for the pika. Pikas, rabbits, and hares constitute the mammalian order Lagomorpha.
Hares are the largest lagomorphs. Depending on the species, the body is about 40–70 cm (16–28 inches) long, with feet up to 15 cm (5.9 inches) long and ears up to 20 cm (7.9 inches) that apparently help dissipate excess body heat. Although usually gray-brown throughout the year, hares living in northern latitudes may turn white in winter (in the far north some remain white all year). One such “varying hare” is the smallest member of genus Lepus, the snowshoe hare (L. americanus) of North America. Most Lepus species have very high rates of reproduction, with multiple large litters being produced each year. Young hares (leverets) are typically born fully furred and with their eyes open and are able to hop a few minutes after birth. Throughout their range, hares are important in the diets of various carnivorous birds, mammals, and reptiles. One of the more dramatic ecological patterns known is the boom-and-bust cycle of snowshoe hare populations in the boreal forests of North America. Populations peak every 8–11 years and then sharply decline, with densities decreasing up to 100-fold. Predation is believed to be responsible for this regular pattern. Lynx populations correlate with those of the snowshoe hare but with a one- to two-year time lag. Lynx eat increasing numbers of hares as they become more common, but, owing to the high rate of predation, lynx numbers drop following the resultant crash in the number of hares. Once hare populations begin to recover, lynx numbers build again, and the cycle is repeated. As hares are almost exclusively herbivorous, they can also dramatically damage natural vegetation or crops when their populations are high. Like rabbits, hares provide people with food and fur.
Hares are the most widespread lagomorph genus, occupying most of North America, Europe, Asia, and Africa. A typical species is the European hare (L. europaeus) of central and southern Europe, the Middle East, and Asia westward into Siberia. The mountain hare (L. timidus) of Asia, the Arctic hare (L. arcticus), and the snowshoe hare live in the far north. Several species of jackrabbit (including L. californicus and L. alleni) are found in the extensive deserts of North America. Many species are abundant throughout their range, including the European hare, which has been introduced into many places, including South America, New Zealand, and Australia, where it has become a pest. In contrast, several hares are endangered, such as the Tehuantepec jackrabbit (L. flavigularis) of southern Mexico, the broom hare (L. castroviejoi) of northern Spain, and the Hainan hare (L. hainanus), which lives on Hainan Island off the coast of southern China.
