The Great Egret (Ardea alba), also known as the Great White Egret, White Heron, or Common Egret, is a wading egret, found in most of the tropical and warmer temperate parts of the world, although it is very local in southern Europe and Asia. It is called Kotuku in New Zealand. It should not be confused with the Great White Heron, which is a white morph of the Great Blue Heron found in Florida.

The Great Egret is a large bird, only slightly smaller than the Great Blue or Grey Herons. It has all white plumage. Apart from size, it can be distinguished from other white egrets by its yellow bill and black legs and feet. It also has a slow flight, with its neck retracted. This is characteristic of herons and bitterns, and distinguishes them from storks, cranes and spoonbills, which extend their necks.


Conservation status

Although generally a very successful species with a large and expanding range, the Great Egret is highly endangered in New Zealand [1], [2]. In North America, large numbers of Great Egrets were killed around the end of the 19th century so that their plumes could be used to decorate hats. Numbers have since recovered as a result of conservation measures. Its range has expanded as far north as southern Canada. However, in some parts of the southern United States, its numbers have declined due to habitat loss. This bird has been chosen as the symbol of the National Audubon Society, which was formed in part to prevent birds from being killed for their feathers. They are Protected in Australia under the National Parks and Wildlife Act, 1974.
