Is a large bird with all white plumage that can reach 101 cm in height and weigh up to 950 g. It is only slightly smaller than the Great Blue or Grey Herons. Apart from size, the Great Egret 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.
