Niche separation in burrowing seabirds in Bass Strait

Abstract

Islands in north-central Bass Strait support significant populations of short-tailed shearwaters, little penguins, fairy prions and common diving-petrels. Dietary analyses showed that while penguins consume mainly fish, the other species primarily feed on krill. Together, these seabirds consume an estimated 1,270,200 tonnes of prey throughout Bass Strait during breeding
