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
In Dalmatia, the golden jackal's diet consists of mammals, fruits, vegetables, insects, birds and their eggs, grasses and leaves. Jackals change their diet to more readily available foods. In Serbia, their diet is primarily livestock carcasses that are increasingly prevalent due to a lack of removal, and this may have led to the expansion of their population. In Hungary, 55% of their diet is composed of common voles and bank voles, and 41% is composed of wild boar carcasses. Information on the diet of the golden jackal in northeastern Italy is scant, but it is known to prey on small roe deer and hares. In Israel, golden jackals are significant predators of snakes; during a poisoning campaign against golden jackals there was an increase in human snakebite reports, but a decrease when the poisoning ceased.
