The streaked shearwater (Calonectris leucomelas) is a species of seabird. The adult bird averages {{convert|48|cm|abbr=on}} in length, with a {{convert|122|cm|abbr=on}} wingspan.

Description

The streaked shearwater feeds mainly on fish and squid. It follows fishing boats, attracted to anchovy crawls off Japan and has been known to be taken as by-catch in nets or drowned when ingesting the bait on long-line fishing lines.

The streaked shearwater nests in burrows. It prefers forested hills.

This bird is abundant and widespread; however, some mortality occurs through becoming entangled in fishing nets, and from some predation by cats and rats. In addition, it is harvested by some traditional endemic human cultures.

Distribution

This species is pelagic, but is also found in inshore waters. It occurs in the Pacific Ocean, nesting in Japan and the Korean Peninsula, predominantly on their offshore islands.{{Cite journal|last=Yamamoto |first=Takashi |s2cid=85046196 |display-authors=etal |year=2010 |title=At-sea distribution and behavior of streaked shearwaters (Calonectris leucomelas) during the nonbreeding period |journal=Auk |volume=127 |issue=4 |pages=871–881 |doi=10.1525/auk.2010.10029|doi-access=free }}{{Cite journal|last1=Sugawa |first1=Hisashi |last2=Karino |first2=Kiyotaka |last3=Ohshiro |first3=Akio |last4=Hirai |first4=Masashi |year=2014 |title=Long-term trends in breeding site fidelity of streaked shearwater Calonectris leucomelas |journal=Marine Ornithology |volume=42 |pages=11–15 |url=http://www.marineornithology.org/PDF/42_1/42_1_11_15.pdf |archive-url=https://web.archive.org/web/20170306170711/http://www.marineornithology.org/PDF/42_1/42_1_11_15.pdf |archive-date=6 March 2017 |url-status=live}}{{Cite journal|last=Hart |first=Kirk A. |display-authors=etal |year=2015 |title=Streaked Shearwaters Calonectris leucomelas of the Korean Peninsula: Distribution, status and potential threats |journal=Forktail |volume=31 |pages=55–63 }}{{refn|group=note|See figure 1 in {{harvnb|Hart|2015|page=56}} for a Korean distribution map.}}{{refn|group=note|South Korean breeding sites include Sasu Island (사수도) and Chilbal Island (칠발도) where they are threatened by rat depredation. {{Cite journal|last1=Lee |first1=Kyung-gyu |last2=Yoo |first2=Jeong-chil |year=2002 |title=Breeding Population of Streaked Shearwaters (Calonectris leucomelas) and the Effect of Norway Rat (Rattus norvegicus) Predation on Sasudo Island|journal=Journal of the Yamashina Institute for Ornithology |volume=33 |issue=2 |pages=142–147|doi=10.3312/jyio1952.33.142 |doi-access=free }}; {{Cite journal|last1=Nam |first1=Ki-Baek |last2=Lee |first2=Kyung-Gyu |last3=Hwang |first3=Jae-Woong |last4=Yoo |first4=Jeong-Chil |year=2014 |title=Variation in Breeding Burrows of Streaked Shearwaters Breeding in Sasu Island, and Predation Rates by Norway Rats |journal= Ocean and Polar Research|volume= 36 |issue=1 |pages=49–57 |doi=10.4217/OPR.2014.36.1.049|doi-access=free }}}} After breeding, the streaked shearwater migrate south, feeding in the seas off northern New Guinea, the Arafura Sea, and the South China Sea.
