The Great Egret is a large bird with all-white plumage that can reach one meter in height and weigh up to 950 grams (2.1 lb). It is thus only slightly smaller than the Great Blue or Grey Heron (A. cinerea). Apart from size, the Great Egret can be distinguished from other white egrets by its yellow bill and black legs and feet, though the bill may become darker and the lower legs lighter in the breeding season.
