Sažetak
In the past fifteen years a considerable increase of golden jackal (Canis aureus aureus) population was perceived on the territory of east Croatia. Since the golden jackal is a predator, it may be concluded that the increased number can cause a significant damage in the hunting grounds, especially by feeding on noble game. For the purpose of verification this assertion and determination of jackal consumption habits, 40 stomachs of the golden jackal were analyzed during the one year period. In that time various remains were found: wild boar hair (in 14 samples), hair and muscle tissue of roe deer (3), small rodents (7), pheasant feathers (1), remains of domestic pigs and poultry (12), vertebrates and their larvae (3), eggs (1), wild and cultivated fruits, (8), corn in different phases of ripening (2), sunflower seeds (1), grains of Amorfa fruticosa (1), leafs of different kinds of grass and herbs (3) and different inorganic litter (plastic foil). It could be presumed that meat and hair were from live (roe dear) or wounded game (wild boar) or those they were eaten after inappropriate disposal of animal remains in their hunting ground. Small rodents originate from animals which jackals caught on agricultural land. It is obvious that golden jackal also uses in its diet different fruits, depending on season and it’s ripening time. It may be concluded that golden jackal is primarily good cleaner in hunting grounds since he uses for its diet carcasses and litter, and only in their absence, he eats the food of non animal origin or hunts for other accessible game which turns him into vermin
in those particular hunting grounds.
