The jackal is an adaptable member of the canine family, representing a group of small-to-medium-sized mammals native to Africa and Eurasia. These resourceful canids thrive in diverse environments, from arid deserts to lush grasslands and human-dominated landscapes. Known for their slender build and opportunistic nature, jackals fill a unique ecological niche as both efficient hunters and proficient scavengers. Understanding the jackal requires looking closely at its classification, physical traits, social behaviors, and varied diet.
Defining the Jackal
The term “jackal” traditionally refers to three distinct species within the family Canidae, which includes wolves, foxes, and domestic dogs. For centuries, all three were placed within the Canis genus alongside the wolf and coyote, but genetic research has since refined this classification.
The Golden Jackal (Canis aureus) of Eurasia is the only species that remains in the Canis genus, and it is genetically more closely related to the gray wolf than to its African counterparts. The two African species—the Black-backed Jackal (Lupulella mesomelas) and the Side-striped Jackal (Lupulella adusta)—have been reclassified into the genus Lupulella. This reclassification reflects their ancient lineage and distant relation to the Golden Jackal. The Black-backed Jackal is sometimes considered the most basal, or oldest, of the wolf-like canids, having changed little since the Pleistocene era.
Appearance and Distribution
Jackals generally exhibit a fox-like appearance, characterized by a slender body, long legs, a pointed muzzle, and large, erect ears. Their long legs and large feet are adapted for endurance running, allowing them to trot over great distances while searching for food. They typically weigh between 15 and 30 pounds, depending on the species, with a body length of about three to three and a half feet.
The three species are readily distinguished by their coats and geographic ranges. The Golden Jackal is the most widespread, found across Southeast Europe, the Middle East, and South Asia, with fur color varying seasonally from pale creamy yellow to darker tawny beige. The Black-backed Jackal is recognizable by a prominent silvery-black saddle running from its shoulders to the base of its tail, contrasting with its reddish-brown flanks, and is found in two separate regions of sub-Saharan Africa. The Side-striped Jackal favors more wooded areas of Central and Southern Africa and features a pale stripe bordered by black along its flanks.
Lifestyle and Behavior
The primary social unit for all jackal species is a monogamous pair that often mates for life. These pairs jointly defend a territory, which they mark with urine and feces to deter rival pairs. The breeding pair and their offspring, sometimes including older young from previous litters, form a small family group that cooperates in raising the pups.
This social structure involves a high degree of cooperation, as older offspring sometimes remain with the parents to assist in provisioning and guarding the new litter, which increases pup survival rates. Jackals communicate using a diverse range of vocalizations, including howls, yips, and growls, which serve to coordinate group activities and establish territorial boundaries. Although they can assemble in small temporary packs to exploit large food sources, they typically hunt and patrol their territory alone or with their partner. They are primarily crepuscular, meaning they are most active during dawn and dusk, though they will hunt during the day if conditions are undisturbed.
Diet and Hunting Strategies
Jackals are highly adaptable omnivores, enabling them to thrive in varied environments across their wide distribution. Their diet is broad, consisting of almost anything readily available, from small prey to plant matter. They hunt small mammals, birds, reptiles, and insects, and also consume fruits and grasses when in season.
As predators, they often employ a combination of speed and endurance, sometimes hunting together in pairs to increase their success rate. While they can take down small ungulates like young gazelles as a team, they primarily focus on smaller prey, which they locate using their acute sense of hearing and smell. Their success is largely due to their role as scavengers, readily consuming carrion left by larger predators. This opportunistic feeding strategy allows them to utilize resources efficiently, helping to clean the ecosystem.
