Baird's beaked whales are found in deep oceanic waters of the North Pacific Ocean and the adjacent Japan, Okhotsk, and Bering Seas. Their range extends to the southern Gulf of California in the eastern Pacific, and to the island of Honshu, Japan in the western Pacific. They may occur in the vicinity of drift ice in the northern Sea of Okhotsk. Off the Pacific coast of Japan, they migrate into waters over the continental slope from May to October, but where they go in winter is not known. They also occur in the Sea of Japan. Their distributional limits in oceanic waters of the mid-Pacific are also not well known (Balcomb 1989; Kasuya 2002).
