Range

The White-faced Storm Petrel boasts a widespread but fragmented breeding distribution across the temperate and subtropical Southern Hemisphere, encompassing islands in the South Atlantic, South Indian, and South Pacific Oceans. Key breeding colonies include Tristan da Cunha, Gough Island, and the...
