It’s a dog eat dog world: observations of dingo (Canis familiaris) cannibalism

摘要

Cannibalism in predators has been reported for a range of species throughout the world, including observations of dingoes (Canis familiaris) eating dingoes in Australia. Here, we report on camera trap observations of dingoes feeding on the carcasses of dingoes and showing aggressive behaviours towards live-trapped conspecifics. At this site, cannibalism and conspecific aggression by dingoes was not caused by food shortages, but was more likely a result of high dingo density in a focal area. We present the first camera trap image observations of dingoes eating dingoes and describe aggressive encounters between live animals.
