Aggressiveĭisplacement of a larger species by a smaller species is an unusual and probably uniquebehavior in carnivores. C.mesomelas was shown to aggressively displace C. adustus differed from allopatric populations in which this species uses grassland, the likely favored habitat for jackals. We radiotracked 22 jackals, 11 Canis mesomelas and 11 Canis adustus, in Hwange, Zimbabwe, to test the hypotheses that habitat use would differ and that the larger C. HABITAT ECOLOGY OF TWO SYMPATRIC SPECIES OF JACKALS Basically, Black-Backed Jackals dominate the approximately 33% larger Side-Striped Jackal. They are considered a serious predator of sheep and are therefore intensively hunted and poisoned.īelow is a study of Black-Backed Jackal interactions with Side-Striped Jackals. Side-striped jackals are not listed by the IUCN Red List. They are nocturnal.įemales have a gestation period of nine weeks, after which they give birth to 3-6 pups. Side-striped jackals live together in pairs, but often hunt in family troops. They feed on small mammals, insects and fruit. Side-striped jackals inhabit open country. They range from Senegal to Somalia, and south to northern Namibia and eastern South Africa. Side-striped jackals are grey with dark stripes on the flanks and a white tip on the tail. Side-striped jackals live for 12-14 years in captivity. Jackals will often follow lions and other big cats to scavenge their kills.
