Muttonbirding is the seasonal harvesting of the chicks of petrels, especially shearwater 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.
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 the Furneaux Group.
[4] Muttonbird may refer to various seabirds, particularly petrels in the genus Puffinus, called shearwaters, 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 on Norfolk Island as the strong taste and fattiness of these birds' meat was likened to mutton.
