Muttonbirding is the seasonal harvesting of the chicks ofpetrels, especiallyshearwater species, for food, oil and feathers by recreational or commercial hunters. Such hunting of petrels and other seabirds has occurred in various locations since prehistoric times, and there is evidence that many island populations have become extinct as a result. More recently ‘muttonbirding’ usually refers to the regulated and sustainable harvesting of shearwaters inAustralia andNew Zealand.[1] These include theshort-tailed shearwater, also known as the yolla or Australian muttonbird, inBass Strait,Tasmania, as well as thesooty shearwater, also known as the tītī or New Zealand muttonbird, on several small islands known as theMuttonbird Islands, scattered aroundStewart Island in the far south of New Zealand.
Licensed commercial harvesting of short-tailed shearwater chicks on the coast and islands of Tasmania began in 1903, although it had long been a traditional form of subsistence harvesting byAboriginal Tasmanians and European settlers there. However, by the late 20th century the industry was declining due to falling demand for the product and reduced interest by younger Indigenous people in the main area of activity, the islands of theFurneaux Group.[2]

The harvesting of sooty shearwater chicks on 36 islands, known as theTītī or Muttonbird Islands, aroundRakiura (Stewart Island), is managed entirely by RakiuraMāori, with about 250,000 being harvested each year.[3] There is some evidence that this harvest has been occurring since at least the 17th century.[4]
Muttonbird may refer to variousseabirds, particularlypetrels in the genusPuffinus, calledshearwaters, where the young birds are harvested for food and oil by being extracted by hand from the nesting burrows before they fledge. The English term "muttonbird" originally emerged among settlers onNorfolk Island as the strong taste and fattiness of these birds' meat was likened to mutton. Others have compared it to fish or seafood in flavour.[3] Some species are:
