 Cormorant Cormorants and Shags are large birds, usually black with some white or
grey. They have a long body shape with short legs and big, webbed feet
set back on the body so as they stand upright when on land, much like
penguins. Unlike most waterbirds, the feathers of cormorants, shags and
darters are not waterproof. This reduces buoyancy, which allows them to
submerge without effort and splashing and with an absence of bubbles;
this means they do not disturb or alert potential prey. However, this
also means they have to ‘hang their wings out to dry’ and are often
seen standing with their wings outstretched. These birds often dive
underwater to catch their prey. They swim by kicking with their big
webbed feet. The wings are tucked by their side and they do not use
them to ‘fly’ underwater like penguins. |
