Both sexes of the horned puffin help to construct their nest. These include Auklets-crumbs, guillemot, spectacled guillemots, lund, and the horned puffin. Rises in ocean temperature have increased the reproductive rate of the horned puffin. The horned puffin is relatively common across its range. Marine birds include tufted and horned puffin, common and thick-billed murre, and marbled murrelets. Horned puffin skins were counted and sold in "knots" or bundles of six. The horned puffin chick has smoky-gray cheeks and a fine, black triangular-shaped beak.
