Cormorant

The cormorant is an excellent fisher. It is most easily spotted when it is perched, stretching its wings out in the sun to dry after a dive. The UK holds internationally important wintering numbers of cormorant.

About

Cormorants are large, black waterbirds. They feed on fish, which they catch with their long, hook-tipped bills while swimming underwater. Cormorants nest on low cliffs around the coasts, or in colonies in trees on lakes and flooded gravel pits. Cormorants can often be spotted perched on a rock or bank with their wings held out. In this stance, they are able to dry their feathers off which are not waterproof.

How to identify

The cormorant is a large, shiny black bird, with a white patch on the thigh during the summer breeding season. Young birds are dark brown above and white below.

Distribution

Found around the coast and on lakes, reservoirs and rivers inland.

Habitats

Did you know?

In China, tame cormorants are used by fishermen as a traditional method of catching fish. A snare is tied around the bird's throat to stop it swallowing bigger fish (although it can still eat small ones), which are then spit up for the fishermen. In different parts of the world, this practice uses different species of cormorant, but it has mostly now become an activity for the tourist industry.
