Cormorant

A diving waterbird in the family Phalacrocoracidae, with a long neck, hooked bill, and often dark plumage. Cormorants pursue fish underwater using their feet for propulsion.

Phalacrocoracidae: A family of aquatic birds that includes cormorants and shags. Cormorants are members of this family, whose species share diving adaptations.
Pursuit diving: A form of underwater foraging in which an animal actively chases prey. Cormorants use pursuit diving to catch fish rather than simply plunging down to seize them.
Cormorant fishing: A fishing practice in which trained cormorants catch fish for people. This traditional practice uses the birds’ underwater hunting ability, often with a ring limiting swallowed prey.
Great cormorant: A widespread cormorant species found across parts of Europe, Asia, Africa, and Australasia. Its broad range and large colonies make it a familiar example of the family.
Cormorant anatomy: The body structures that support a cormorant’s aquatic life, including its hooked bill and webbed feet. These features let cormorants catch fish and propel themselves underwater.
Webbed feet: Feet joined by skin that increases the surface area available for swimming. Cormorants propel themselves underwater mainly with their powerful webbed feet.
Fisheries: The harvesting and management of wild fish populations and other aquatic resources. Cormorants can compete with fisheries for fish, making their ecological effects a management concern.
Double-crested cormorant: A North American cormorant species named for the paired crests shown during breeding. It is a prominent species in North American fisheries and wildlife-management debates.
Waterbird: A bird adapted to live on or around freshwater or marine habitats. Cormorants are waterbirds, but their pursuit-diving lifestyle is especially distinctive.
Wing-drying posture: A posture in which a cormorant spreads its wings, commonly after swimming or diving. The conspicuous pose is linked to waterlogged plumage and helps the feathers dry.
