To Labuan Island it is a common non-breeding visitor every year. The Old World population is often referred to as the great white egret”. This species is sometimes confused with the great white heron of the Caribbean, which is a white morph of the closely related great blue heron. The great egret is a large heron with all-white plumage. 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. In breeding plumage, delicate ornamental feathers are borne on the back. Males and females are identical in appearance; juveniles look like non-breeding adults. Differentiated from the intermediate egret (Mesophoyx intermedius) by the gape, which extends well beyond the back of the eye in case of the great egret, but ends just behind the eye in case of the intermediate egret. – based on a Wikipedia article.
