23 inches. Male and female identical in appearance. Multiphase species with individuals with white feathers or grey plumage. White egrets are more common in the Tuamotu where the sand is clear while the grey egrets dominate the volcanic islands, where they hunt on black sand beaches and mudflats. It is a large wading bird with yellow legs. Its beak is strong and straight and its colour varies from black to pink. Its very characteristic long neck is folded in flight and sometimes at rest. Its silhouette can then be confused in Tahiti with that of the Striated Heron (Green-backed Heron), Butorides striatus, whose neck is very short.
