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 island. After breeding, the streaked shearwater migrate south, feeding in the seas off northern New Guinea, the Arafura Sea, and the South China Sea. I am not sure whether they fly over to Strait of Malacca at the narrowest section of Thailand peninsula to Andaman seas then down south.

This shearwater has broad wings with a brown upper side and white underwings. The head and neck are flecked white to almost complete white. The face and underparts are all white. The bill is grey to pink with a dark tip while the feet are pinkish-grey.
Streaked shearwaters have a body length (from tip of bill to end of tail feathers) of 45 to 52 centimetres (18 to 20 in) and a wingspan between 103 and 113 centimetres (41 and 44 in).
The streaked shearwater feeds mainly on fish and squids. 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.
