The storm-petrels are small seabirds.These smallest of seabirds feed on planktonic crustaceans and small fish picked from t he surface, typically while hovering. The flight is fluttering and sometimes bat-like.
Storm-petrels have a cosmopolitan distribution, being found in all oceans. They are strictly pelagic, coming to land only when breeding. In the case of most species, little is known of their behaviour and distribution at sea, where they can be hard to find and harder to identify.
