CONSERVATION STATUS

Near Threatened

The Cape Verde Shearwater is a species of shearwater that breeds on a few islands in the Cape Verde archipelago off of the Senegalese coast. After breeding, it mostly occurs in pelagic waters of the Atlantic Ocean off the west African coast. It has also been recorded as a vagrant off the Atlantic coast of eastern North America. It forages for fish, squid, and small marine creatures on and near the surface of deep water and nests on rocky islands. The Cape Verde Shearwater is given a conservation rating of Near Threatened due to over harvesting of young birds.
