Both the silver gull (Larus novaeholandiae) and the Australian raven (Corvus coronoides) have been observed preying on mountain duck (Tadorna tadornoides) nests on Rottnest Island, but it is felt that those birds were drawn to nesting burrows by the presence of investigators. The author believes predators were searching for food scraps and inadvertently discovered duck nests.
