The Golfo Corcovado and Guafo mouth area is located south of the big Chiloe island in Chile. It is an important area for marine mammals, including threatened species. It is noteworthy as the breeding site and foraging ground of a recently discovered blue whale population. This area is home to the largest sooty shearwater colony in the world.
