Streaked Shearwaters Calonectris leucomelas

The Streaked Shearwater, Calonectris leucomelas, is a species of seabird.


The bird is 48 cm in size, with a 122 cm wingspan.

This species is pelagic (over sea), but also occurs in inshore waters.


It occurs in the Pacific Ocean, nesting in Japan and many of its offshore islands. After breeding, the Streaked Shearwater will migrate toward southern Australia. It has been reported well off the west coast of the United States.

Diet / Feeding

The Streaked Shearwater feds mainly on fish and squid. It does follow fishing boats, attracted to anchovy crawls off Japan.


Streaked Shearwater uses burrows to nest in. 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.
