Cormorant
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.

Birds

Herons
Egret
Egret
This group includes the herons, night herons, egrets and bitterns. All of these birds are in the heron family, and the terms ‘heron’ and ‘egret’ are often used interchangeably and mean different things in different parts of the world for different people. They are only common names and do not currently correspond to any scientific or biological grouping. The original historical definition of the name 'egret' came from certain species of white egrets that were hunted for their filamentous plumes, or 'aigrette' and this is where the name egret come from. Many of the Ardea species are large, rather elegant mainly whitish birds that all look rather similar. They usually wade through shallow water in slow movements, often freezing, looking for fish and other underwater prey and snatching them suddenly with sharp beaks.
