Side-striped jackal

Appearance

The side-striped jackal is a medium-sized canid, which tends to be slightly larger than the black-backed jackal. Its pelt is coloured buff-grey. The back is darker grey than the underside, and the tail is black with a white tip. Indistinct white stripes are present on the flanks, running from elbow to hip. The boldness of the markings varies between individuals, with those of adults being better defined than those of juveniles.

The side-striped jackal's skull is similar to that of the black-backed jackal's, but is flatter, with a longer and narrower rostrum. Its sagittal crest and zygomatic arches are also lighter in build. Due to its longer rostrum, its third upper premolar lies almost in line with the others, rather than at an angle. Its dentition is well suited to an omnivorous diet. The long, curved canines have a sharp ridge on the posterior surface, and the outer incisors are canine-like. Its carnassials are smaller than those of the more carnivorous black-backed jackal. Females have four inguinal teats. The side-striped jackal's dental formula is:

Naming

There are six recognized subspecies of this jackal:

⤷ ''Canis adustus adustus''
⤷ ''Canis adustus bweha''
⤷ ''Canis adustus grayi''
⤷ ''Canis adustus kaffensis''
⤷ ''Canis adustus lateralis''
⤷ ''Canis adustus notatus''

Behavior

The side-striped jackal lives both solitarily and in family groups of up to seven individuals. The family unit is dominated by a breeding pair, which remains monogamous for a number of years.

The breeding season for this species depends on where they live; in southern Africa, breeding starts in June and ends in November. The side-striped jackal has a gestation period of 57 to 70 days, with average litter of three to six young. The young reach sexual maturity at six to eight months old, and typically begin to leave when 11 months old. The side-striped jackal is among the few mammal species that mate for life, forming monogamous pairs.

Food

The side-striped jackal tends to be less carnivorous than other jackal species, and is a highly adaptable omnivore whose dietary preferences change in accordance to seasonal and local variation. It tends to forage solitarily, though family groups of up to 12 jackals have been observed to feed together in western Zimbabwe. In the wild, it feeds largely on invertebrates during the wet season and small mammals, such as the springhare, in the dry months. It frequently scavenges from campsites and the kills of larger predators. In the wild, fruit is taken exclusively in season, while in ruralised areas, it can account for 30% of their dietary intake. The side-striped jackal tends to be comparatively less threatening to game and livestock when compared to other jackal species. It typically does not target game exceeding the size of neonatal antelopes, and one specimen was recorded to have entered a duck's pen to eat their feed, whilst ignoring the birds.
