The Short-tailed Shearwater or Slender-billed Shearwater (Puffinus tenuirostris), also called Yolla or Moonbird, and commonly known as the muttonbird in Australia, 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. In New Zealand the Sooty Shearwater is the local 'muttonbird', and other harvested petrel species, such as the Wedge-tailed Shearwater, may be known as muttonbirds elsewhere.
