Cook's petrel is a small seabird from the storm petrel family. It spends almost its entire life flying over the Pacific Ocean and comes to the islands only to raise chicks.
Cook's petrel differs from other petrels in its small body size and light color of the underwing. It is important for nature as a participant in ocean food chains and an indicator of the purity of marine waters.
