The great egret Ardea alba, also known as the common egret, large egret, or in the Old World great white egret or great white heron is a large, widely distributed bird, with four subspecies found in Asia, Africa, the Americas, and southern Europe. Distributed across most of the tropical and warmer temperate regions of the world, it builds tree nests in colonies close to water. The great egret is a large heron with all-white plumage. It has a slow flight, with its neck retracted. This is characteristic of herons and bitterns, and distinguishes them from storks, cranes, ibises, and spoonbills, which extend their necks in flight. The great egret walks with its neck extended and wings held close. The great egret is partially migratory, with northern hemisphere birds moving south from areas with colder winters. It is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds AEWA applies.The young are fed by regurgitation by both parents and they are able to fly within 6–7 weeks. The great egret feeds in shallow water or drier habitats, feeding mainly on fish, frogs, small mammals, and occasionally small reptiles and insects, spearing them with its long, sharp bill most of the time by standing still and allowing the prey to come within its striking distance of its bill, which it uses as a spear. It often waits motionless for prey, or slowly stalks its victim.
