The short-tailed shearwater or slender-billed shearwater (Ardenna tenuirostris; formerly 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.
Many shearwaters are long-distance migrants, perhaps most spectacularly sooty shearwaters, which cover distances in excess of 14,000 km (8,700 mi) from their breeding colonies on the Falkland Islands (52°S 60°W) to as far as 70° north latitude in the North Atlantic Ocean off northern Norway, and around New Zealand to as far as 60° north latitude in the North Pacific Ocean off Alaska.
The wedge-tailed shearwater (Ardenna pacifica) is a medium-large shearwater in the seabird family Procellariidae. It is one of the shearwater species that is sometimes referred to as a muttonbird , like the sooty shearwater of New Zealand and the short-tailed shearwater of Australia .
Translocation of chicks to establish new breeding colonies is also part of long-term strategy to restore the environment, including offshore islands that were once farmed but are now protected areas. Between 1991 and 1996, 334 fluttering shearwater chicks were moved from Long Island in the Marlborough Sounds to Maud Island. Artificial burrows ...
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.
Puffinus gravis, great shearwater breeds on islands in the South Atlantic Ocean; ranges in the North Atlantic Ocean to the Arctic Circle; Puffinus pacificus, wedge-tailed shearwater ranges through tropical Pacific Ocean and Indian Ocean; Puffinus bulleri, Buller's shearwater breeds on islands off the coast of New Zealand; ranges across the ...
The large chicks of the Manx shearwater are very rich in oil from their fish diet and have been eaten since prehistoric times. They are easily extricated from their burrows, and the annual crop from the Calf of Man may have been as high as 10,000 birds per year in the 17th century.
A semi-precocial wedge-tailed shearwater chick with guarding parent. The majority of procellariiforms nest once a year and do so seasonally. [69] Some tropical shearwaters, like the Christmas shearwater, are able to nest on cycles slightly shorter than a year, and the large great albatrosses (genus Diomedea) nest in alternate years (if ...
