Species: Oceanodroma furcata

H - >2,500,000 square km (greater than 1,000,000 square miles) - H - Breeding occurs in the North Pacific from southern Alaska south along west coast of North America to islets off northern California, and from Commander Islands south to the Kurile Islands. At sea, the species ranges from western Alaska south through Bering Sea and North Pacific coastally to central California (rare), and to Hawaii, Marcus Islands, Japan. It is most abundant in the northern parts of the range; offshore islands of Alaska, especially the eastern Aleutians, contain the core of species' breeding distribution. When not breeding, birds appear to disperse to deeper water near breeding grounds; they are often associated with the continental shelf break (Boersma and Silva 2001).
