Range and Habitat
Streaked Shearwater: Breeds in large numbers on islands of southern Japan. In autumn may be seen in Hawaii and, occasionally, off the coast of California. Pelagic, comes ashore only to breed.
The Streaked Shearwater uses burrows to nest in. It prefers to dig them on forested hills.
They are abundant and widespread, however some mortality occurs from entanglement in fishing nets, and from predation by cats and rats. In addition, it is harvested by some traditional endemic human cultures.
A group of shearwaters are collectively known as an "improbability" of shearwaters.
