storm-petrel

The storm-petrels are  seabirds in the family Hydrobatidae, part of the order Procellariiformes. These smallest of seabirds feed on planktonic crustaceans and small fish picked from the 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. They are colonial nesters, displaying strong philopatry to their natal colonies and nesting sites. Most species nest in crevices or burrows and all but one species attends the breeding colonies nocturnaly. Pairs for long term monogamous bonds and share incubation and chick feeding duties. Like many species of seabird nesting is highly protracted with incubation taking up to 50 days and fledging another 70 days after that.
