About the Streaked Shearwater
The streaked shearwater is a long-winged seabird that spends most of its life at sea, coming ashore on islands during the breeding season to nest in burrows. It returns to its colony at night, making distinctive calls. It breeds on islands from Hokkaido to Okinawa, and some important breeding sites, including sites in Iwate, Niigata, Kyoto, Shimane and Okinawa, are designated Natural Monuments.

Swinhoe's Storm Petrel is a small storm petrel, dark brown nearly all over. It feeds at sea on small plankton and fish and comes ashore to breed in burrows. Sanganjima in Iwate is known as a site where it breeds together with Streaked Shearwaters, and the colony is designated a national Natural Monument.
