Horned Puffin (Fratercula corniculata) The species is widespread in the North Pacific Ocean. It nests on coastlines and offshore islands from British Columbia (where they are rare) to Alaska, and southwest to the Sea of Okhotsk and the Kuril Islands. In Alaska, the largest colonies are concentrated in the northwest Gulf of Alaska and along the Alaska Peninsula. The horned puffin population is estimated at 1.2 million. Their diet consists of: Herring, capelin, sandlance, anchovies, rockfish, and sculpin and some invertebrates, such as shrimp and krill. This species is pelagic, living on the open sea for majority of its lifetime. During the non-breeding season (juvenile years and adult winters), this species is found throughout the waters of the north Pacific. They nest in crevices and burrows on sea cliffs.
