Latin Name: Canis mesomelas
Afrikaans: Rooijakkals
Distribution in South Africa
Black-backed Jackal are distributed throughout South Africa
Black- backed Jackals occur in most habitats from desert to mountains to coastal areas. They prefer drier areas and tend to avoid marshy areas and wetlands.
They live in pairs that form long term bonds and establish territories, but more often than not scavenge and hunt alone. They are extremely cunning and very adaptable.
Day or night
Although they are at times also active during the day, they usually rest up in holes dug by other species such as ant bears (aardvark), as well as in other shelters like rock crevices, under bushes etc. Black-backed Jackals are mostly active at night and are often seen at dusk and dawn. In protected areas and reserves they are also active on cool overcast days, but in areas where they are persecuted by man they tend to be shy and hide away.
Difference between male and female
Males are larger than females.
Male: 6 to 11 kg. 
Female: 5 to 10 kg
About 12 years
Mating takes place during the winter months. The average litter are between 1 and 6, but sometimes (although very seldom) up to 9 or 10 cubs, are born from July to November depending on the region, area and rains.
About 2 months
Diet - Food and water
They are hunters and scavengers with a very acute sense of smell. Their diet consists of a wide range of food including small antelope, hares, reptiles, rodents, insects, birds and eggs. Some types of wild fruit and berries (The Jackal berry tree is named after them) that have fallen to the ground are also eaten. Newborn calves of cattle, sheep (lambs) and young goats are often killed by them as well as chickens. They also scavenge for carrion. Because of their adaptability, Black-back Jackals are not really water dependent, but will drink water on a regular basis if available.
Lions, Leopards, Hyena, Cheetah and other Jackal will often kill their cubs if found. Large eagles also sometimes take young jackals and pythons are also a danger to jackals. Humans are most probably their greatest enemy.
They still occur in large numbers throughout South Africa. In farming areas they are considered as pests and many are killed daily. However they are safe from persecution in wildlife and nature reserves, as well as in National Parks.
Interesting facts
The haunting call of the Black–backed Jackal is part of the wonderful array of sounds to be heard in the African bush at night and is one of the typical night sounds of wilderness areas.
Due to stock losses (chicken, lamb and small goats), many farmers have no love at all for this animal and in some areas they have eradicated them with poison, gin traps and by hunting them, especially with dogs.
