The Masatierra storm petrel is a small seabird from the storm petrel family. It lives in the Pacific Ocean and nests only on Mas-a-Tierra Island off the coast of Chile.
The Masatierra storm petrel differs from other storm petrels by its special light pattern on the wings and smaller size. It is important for nature as a carrier of nutrients from the ocean to the islands and serves as an indicator of the purity of marine waters.
