Feeding-Behavior and Diet of Dingoes in the Nullarbor Region, Western-Australia

Abstract

Observations were made on the diet and feeding behaviour of the dingo (Canis familiaris dingo) in the Nullarbor region of Western Australia. Mammal species accounted for 96% of food items identified in diet samples. Rabbits (Oryctolagus cuniculus) and red kangaroos (Macropus rufus) were the most frequently occurring prey items. Cattle (Bos taurus) carrion, although available, was a relatively minor part of the diet. Foxes (Vulpes vulpes), cats (Felis catus), birds, reptiles and arthropods were eaten only occasionally. Dingoes usually hunted alone, and solitary dingoes were more successful in hunting rabbits than were members of groups. Only solitary dingoes were seen to chase and catch kangaroos, but kangaroo carcasses were often shared. We suggest that the widespread solitary foraging characteristic of dingoes on the Nullarbor may be related to their reliance on rabbits as the dietary staple.
