glareolus

Glareolus is a genus of birds in the family Alcidae, which includes auks and puffins. The genus contains two species, the Atlantic puffin (Glareolus maritimus) and the horned puffin (Glareolus atlantis). Both species are medium-sized seabirds with distinctive beaks and crests. The Atlantic puffin is found in the North Atlantic Ocean, breeding on islands and coastal cliffs, while the horned puffin is found in the North Pacific Ocean, breeding on offshore islands. Both species are known for their distinctive calls and are important indicators of the health of marine ecosystems. They feed primarily on fish and squid, which they catch by diving from the surface of the water. Glareolus species are protected under various international agreements, including the Agreement on the Conservation of Albatrosses and Petrels.
