Goliath Heron

Ardea goliath

Huge4.5 kgWetland

It is the world's largest living heron (though the extinct Bennu heron was larger). The height of the goliath heron is 120–152 cm (3 ft 11 in – 5 ft 0 in), the wingspan is 185–230 cm (6 ft 1 in – 7 ft 7 in) and the weight is 4–5 kg (8.8–11.0 lb). The tarsus measures from 21.2 to 25.5 cm (8.3 to 10.0 in) and the wing chord averages around 60.7 cm (23.9 in) in length. The culmen measures from 18 to 20 cm (7.1 to 7.9 in), while the bill from the gape measures around 24 cm (9.4 in). In flight it has a slow and rather ponderous look and, unlike some other herons, its legs are not held horizontally.
