普通鵜燕

<em>Pelecanoides urinatrix</em>, the common diving petrel, is a seabird in the family Procellariidae distributed across the Southern Ocean and subantarctic regions, with records extending to Norway. This species typically inhabits open marine environments and coastal cliffs, where it nests in burrows on islands and steep shorelines. The common diving petrel is notable for its highly specialized diving behavior, using its wings to propel itself underwater in pursuit of small fish, crustaceans, and zooplankton. Its compact body, short wings, and strong feet make it well adapted to both aerial and aquatic locomotion, though flight is typically low and whirring. <em>Pelecanoides urinatrix</em> is generally nocturnal at its nesting colonies, helping to reduce predation risk. Adults typically form long-term pair bonds and raise a single chick per breeding season in underground burrows. The species is assessed as Least Concern, though some island populations have experienced pressure from introduced predators. Its ecology reflects a highly marine-adapted lifestyle across cold southern waters.
