Two species of jackal occur in Kruger. The black-backed jackal is the more common and is often seen in the central grasslands. The side-striped jackal generally avoids the open plains and is more of a woodland animal that also favours the Lebombo. Jackals are usually solitary animals, scavenging by night and in the early morning. They are sometimes found in family packs and in such cases hunt impala and smaller antelope. They are particularly fond of ostrich eggs.
