The marabou stork (Leptoptilos crumenifer) is a wading bird in the stork family, Ciconiidae, native to sub-Saharan Africa. It is a large bird, with individuals reaching a height of 152 centimetres (4.99 feet) and a weight of 9 kilograms (20 lb), and has the largest wingspan of any land bird, with an average of 2.6 metres (8.5 ft) and some recorded examples of up to 3.2 metres (10 ft). The marabou stork breeds in Africa south of the Sahara. In East Africa, the birds interact with humans and breed in urban areas. In southern African countries, the birds breed mainly in less populated areas. This marabou stork in flight was photographed in the town of Batu, by Lake Ziway, Ethiopia.Photograph credit: Charles J.
