Goliath Heron (Ardea goliath)

The Goliath Heron (Ardea goliath) is a large wading bird of the heron family Ardeidae. It is found in sub-Saharan Africa, with smaller numbers in Southwest and South Asia.


This is the world's largest heron. The height is 120–152 cm (47–60 in), the wingspan is 185–230 cm (73–91 in) and the weight is 4–5 kg (8.8–11 lbs). In flight it has a slow and rather ponderous look and, unlike some other herons, its legs are not held horizontally. Male and female look similar, with an overall covering of slate gray and chestnut feathers.


The head and its bushy crest, face, back and sides of the neck are chestnut. The chin, throat, foreneck and upper breast are white, with black streaks across the foreneck and upper breast. 


The lower breast and belly are buff with black streaks. The upper mandible is black and the lores and orbital areas are yellow with a greenish tinge. The eyes are yellow and legs and feet are black. Juveniles look similar to the adults, but are paler.



Important habitats are lakes, swamps, mangrove wetlands, with few cool water, sometimes river deltas.
Goliath Herons feed on fish, frogs, small mammals and insects. A diurnal and often rather inactive feeder, this heron hunts by standing in the shallows, or on floating vegetation, intently watching the water at its feet. As prey appears, the heron rapidly spears it with open mandibles.
Its breeding season is from November to March. These birds build a large stick nest in trees overhanging water, on the ground and in low bushes.
