CONSERVATION STATUS

Least Concern

The Tropical Shearwater has a large range of 46,000,000 square kilometers. Much of this distribution includes pelagic waters, including the waters around Palau. It breeds on several small islands in the tropical Pacific and Indian Oceans. Although the global population for the Tropical Shearwater is unknown, it is believed to be large and stable enough to warrant a conservation rating of Least Concern.
