The antelope jackrabbit (Lepus alleni ) is a species of North American hare found in southern Arizona and northwestern Mexico that occupies dry desert areas.


The Antelope jackrabbit is a North American hare named after the fast-running antelope. These animals are also known for being able to run and leap quickly. Like antelopes, these hares also show flashes, as they run, of their white underside. They are one of five species of jackrabbit that inhabit different regions of North America. They are one of the biggest hares in this region and are larger than rabbits. They make their nests above ground.



Antelope jackrabbits are found mostly along Mexico’s western coast, in the states that are alongside the Pacific Ocean and the Gulf of California. They are also found in Arizona (USA) in a small southern area, mainly in the Sonoran Desert. This species also inhabits Tiburon, a small island near Sonora, a Mexican state. In Arizona, they are typically found in places where grass is growing well under moderately high and open desert shrubs. In Mexico, they like open and low grasslands, and also foothills with patchy grass and low bushes, and are most common in coastal foothills.

Habits and Lifestyle

Antelope jackrabbits are solitary, nocturnal and crepuscular, but may be active on cloudy days during the day. In the hot season they spend their days staying out of the heat in what are known as "shelter forms," which they create by backing up under weeds, grass, or brush, or simply sitting under the shade of a mesquite trunk or cactus, preferring mesquite or creosote bush. Such shelter helps to deal with the extreme heat of the day. As jackrabbits are coprophagic (i.e. they eat their own feces), the shelter forms might also help them with re-digestion of pellets, through making it safer for them to sit and digest. As with other jackrabbits, antelope jackrabbits live solitary lives. Their long ears enable them to take in their surroundings and listen for predators. In rare circumstances they will use sound to communicate. They may use a pheromone from a rectal gland which secretes a strong musky smell to scent mark their shelter form.

Seasonal behavior

Diet and Nutrition

Antelope jackrabbits are folivores (leaf-eaters), graminivores (grass-eaters) and succulent plant eaters (esp. cacti). They mainly eat fresh grass and other types of vegetation. During a drought they will eat cacti and shrubs, such as mesquite and creosote. They do not drink water directly, but get it from what they eat, especially cacti stems.

Mating Habits

late December-September
6 weeks
1-5 leverets
at birth

Antelope jackrabbits are polygynous breeders. This means that one male will mate with more than one female. During the breeding season, the males may fight with one another, kicking with their hind feet and boxing with their forefeet over access to females. Breeding take place from late December until September. 3 to 4 litters can be produced each year if conditions are good. Gestation lasts about 6 weeks, and there are usually 2 young per litter, but 1 to 5 young may be born. At birth they are well-developed (precocial) and at just a few days old they are weaned and independent. It is thought that mothers hide their young in different places after birth, returning to feed them at night. Fathers do not help with caring for their young. Antelope jackrabbits become reproductively mature at 2 years of age.


Population threats

The main threat to this species is habitat loss. Human impacts on their habitat include housing developments, livestock grazing, recreational trails, and the building of canals. In particular, in southern Arizona their habitat is threatened by a non-native grass species, Lehmann lovegrass, which they cannot eat. Hunting for local subsistence and sport, human influence and exotic predation are further threats. In some places, competition from livestock, habitat fragmentation and fires caused by humans are important threats.

Population number

According to IUCN, the Antelope jackrabbit is common and widespread throughout its range but no overall population estimate is available. Currently this species is classified as Least Concern (LC) on the IUCN Red List and its numbers today remain stable.

Ecological niche

Antelope jackrabbits are important prey for medium to large terrestrial and avian predators.

Fun Facts for Kids

  • The Antelope jackrabbit gets its name from John Asaph Allen, a past curator at the American Museum of Natural History’s Department of Mammals and Birds.
  • The name ‘jackrabbit’ is thought to be due to the large size of this animal’s ears. According to locals, their ears look like donkey ears. Therefore, the early settlers called it ‘jackass rabbit’, later shortened to ‘jackrabbit’. Basically, a jackrabbit is a large-eared hare with long hind legs.
  • The Antelope jackrabbit’s ears are not only used for hearing, but also to regulate and reduce body heat for survival during hot conditions.
  • Jackrabbits are often seen as pests because they can destroy crops quickly. They have a big appetite and can eat one pound of food in a day.
  • Jackrabbits are agile and fast. They can jump 10 feet and run at 40 miles per hour. They tend to jump in a zigzag pattern to confuse predators and have an opportunity to escape.
