Short-tailed shearwater

The short-tailed shearwater or slender-billed shearwater (Ardenna tenuirostris), also called yolla or moonbird, and commonly known as the muttonbird both in early Australia and in New Zealand, is the most abundant seabird species in Australian waters, and is one of the few Australian native birds in which the chicks are commercially harvested. It is a migratory species that breeds mainly on small islands in Bass Strait and Tasmania and migrates to the Northern Hemisphere for the boreal summer.
