with age and location. Adult puffins largely depend on invertebrates, especially squid and krill. Nestlings at coastal colonies are fed primarily fish such as rockfish and sandlance, while nestlings at colonies closer to pelagic habitats are more dependent on invertebrates. Demersal fish are consumed in some quantity by most nestlings, suggesting that puffins feed to some extent on the ocean bottom. Feeding areas can be located far offshore from the nesting areas. Puffins can store large quantities of small fish in their bills and carry them to their chicks. Predators and threats Tufted puffins are preyed upon by various avian raptors such as snowy owls, bald eagles and peregrine falcons, and mammals like the Arctic fox. Foxes seem to prefer the puffin over other birds, making the bird a main target. Choosing inaccessible cliffs and entirely mammal-free islands protects them from terrestrial predators while laying eggs in burrows is effective in protecting them from egg-scavengers like gulls and ravens. A mass die-off of puffins at St. Paul Island, Alaska between October 2016 and January 2017 has been attributed to ecosystem changes resulting from climate change. Relationship with humans The Aleut and Ainu people (who called them Etupirka) of the North Pacific traditionally hunted tufted puffin for food and feathers. Skins were used to make tough parkas worn feather side in and the silky tufts were sewn into ornamental work. Currently, harvesting of tufted puffin is illegal or discouraged throughout its range. The tufted puffin is a familiar bird on the coasts of the Russian Pacific coast, where it is known as toporok (Топорок) – meaning "small axe," a hint to the shape of the bill. Toporok is the namesake of one of its main breeding sites, Kamen Toporkov ("Tufted Puffin Rock") or Ostrov Toporkov ("Tufted Puffin Island"), an islet offshore Bering Island. The oldest recorded tufed puffin was six years old when discovered in Alaska, the same state where it had been banded. Conservation status in Puget Sound Many rules and regulations have been set out to try to conserve fishes and shorebirds in Puget Sound. The Department of Natural Resources (DNR) of Washington State has created aquatic reserves surrounding Smith and Minor Islands. Over of tidelands and seafloor habitat were included in the proposed aquatic reserve. Not only do these islands provide the necessary habitat for many seabirds such as tufted puffins and marine mammals, but this area also
