Schlegel's Petrel is a seabird from the storm-petrel family. It spends almost its entire life flying over the waters of the Atlantic Ocean and comes to islands only to breed.
Schlegel's Petrel is distinguished by its dark upper body and white underparts. It transfers nutrients from the ocean to islands and serves as an indicator of the marine ecosystem's health.
