It is a large bird, standing up to 100 cm (39 in) tall and measuring 84–102 cm (33–40 in) long with a 155–195 cm (61–77 in) wingspan. The body weight can range from 1.02–2.08 kg (2.2–4.6 lb). Its plumage is largely grey above, and off-white below. Adults have a white head with a broad black supercilium and slender crest, while immatures have a dull grey head. It has a powerful, pinkish-yellow bill, which is brighter in breeding adults. It has a slow flight, with its long neck retracted (S-shaped). This is characteristic of herons and bitterns, and distinguishes them from storks, cranes and spoonbills, which extend their necks. The call is a loud croaking "fraaank". The Australian White-faced Heron is often incorrectly called Grey Heron. In Ireland the grey heron is often colloquially called " crane ". It feeds in shallow water, catching fish, frogs, and insects with its long bill. Herons will also take small mammals, reptiles and occasionally warbler nestlings, plovers, young and adult snipes, takes ducklings and tern chicks and other small birds.[4] It will often wait motionless for prey, or slowly stalk its victim. In the Netherlands, the Grey Heron has become a very common species in recent decades by moving into urban environments in great numbers. There, the herons hunt as they usually would but also make use of food discarded by humans, will visit feeding times in zoos to birds such as penguins and pelicans and some individuals even make use of people feeding them at their homes. Similar behaviour on a smaller scale has been reported in Ireland.
