European jackal
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
Golden jackal
The golden jackal can be a harmful pest that attacks domestic animals such as turkeys, lambs, sheep, goats, domestic water buffalo calves, and valuable game species like newborn roe deer, hares, coypu, pheasants, francolins, grey partridges, bustards and waterfowl. It destroys grape, coffee, maize, sugarcane, and eats watermelons, muskmelons, and nuts. In Greece, golden jackals are not as damaging to livestock as wolves and red foxes but they can become a serious nuisance to small stock when in great numbers. In southern Bulgaria, over 1,000 attacks on sheep and lambs were recorded between 1982 and 1987, along with some damage to newborn deer in game farms. The damage by jackals in Bulgaria was minimal when compared to the livestock losses due to wolves. Approximately 1.5–1.9% of calves born in the Golan Heights die due to predation, mainly by jackals. The high predation rate by jackals in both Bulgaria and Israel is attributable to the lack of preventative measures in those countries and the availability of food in illegal garbage dumps, leading to jackal population explosions.
