Jackrabbits are real animals, a fascinating part of North American wildlife. Often seen bounding across open landscapes, their distinctive appearance and remarkable speed make them a subject of curiosity.
Understanding Jackrabbits
Jackrabbits are not true rabbits but a type of hare (Lepus genus). While in the same family (Leporidae), hares and rabbits have distinct differences. The name “jackrabbit” originated from “jackass rabbit,” referencing their long, donkey-like ears.
They are recognized by exceptionally long ears, up to 7 inches, and powerful hind legs. Their lean, muscular bodies typically weigh between 3 and 9 pounds and reach lengths of 18 to 28 inches. Their fur, often gray to brown, provides camouflage and can change seasonally in some species.
Life in Their Habitat
Jackrabbits inhabit open environments like grasslands, deserts, and prairies across the western United States and Mexico. They prefer areas with mixed vegetation, offering food and cover. As herbivores, their diet includes shrubs, grasses, and forbs, adapting based on seasonal availability. They obtain most water from plants, enabling survival in arid regions.
Survival in their open habitats relies heavily on their remarkable speed and evasive behaviors. Jackrabbits can reach speeds of up to 45 miles per hour and leap impressive distances of over 10 feet. When threatened, they employ a zigzag running pattern, which helps confuse predators like coyotes, foxes, and eagles. Their large ears also serve a dual purpose, not only providing acute hearing for predator detection but also helping to regulate body temperature in warm climates by dissipating heat.
Jackrabbits Versus Rabbits
Despite their common name, jackrabbits are fundamentally different from true rabbits. Biologically, jackrabbits are hares (Lepus genus), while true rabbits belong to other genera like Sylvilagus (cottontails) or Oryctolagus (domestic rabbits). This distinction leads to several key differences in their physical characteristics and behavior.
Hares, including jackrabbits, are generally larger with leaner bodies, longer ears, and more powerful hind legs compared to rabbits. A notable difference lies in their young: jackrabbit “leverets” are born precocial, meaning they are fully furred, have open eyes, and are mobile shortly after birth. In contrast, rabbit “kits” are born altricial, arriving blind, hairless, and completely helpless, requiring significant parental care in a nest. Jackrabbits do not build elaborate burrows; instead, they typically rest in shallow depressions called “forms” or under vegetation. Rabbits, conversely, often live in underground burrows, sometimes in complex systems known as warrens, and tend to be more social than the solitary or paired jackrabbits.
