The Wattled Crane, Bugeranus carunculatus is a large bird found in Africa south of the Sahara Desert. It is monotypical for its genus.
At a height of up to 175 cm (nearly 6 feet), it is the largest crane in Africa and is the second tallest species of crane, after the Sarus Crane. The wingspan is 230-260 cm (90-102 in), the length is typically 120 cm (47 in) and weight is 6.4-7.9 kg (14-17.6 lbs) in females, 7.5-9 kg (16.5-20 lbs) in males. The back and wings are ashy gray. The feathered portion of the head is dark slaty gray above the eyes and on the crown, but is otherwise white, including the wattles, which are almost fully feathered and hang down from under the upper throat. The breast, primaries, secondaries, and tail coverts are black. The secondaries are long and nearly reach the ground. The upper breast and neck are white all the way to the face. The skin in front of the eye extending to the base of the beak and tip of the wattles is red and bare of feathers and covered by small round wart-like bumps. Wattled Cranes have long bills and black legs and toes. Males and females are virtually indistinguishable, although males tend to be slightly larger.
Juveniles have tawny body plumage, lack the bare skin on the face, and have less prominent wattles.
Range
The Wattled Crane occurs in eleven sub-Saharan countries in Africa, including an isolated population in the highlands of
Ethiopia. More than half of the world’s Wattled Cranes occur in
Zambia, but the single largest concentration occurs in the
Okavango Delta of
Botswana. Wattled Cranes are thought to have historically ranged over a much larger area including coastal
West Africa.
Diet
All cranes are
omnivorous. The principal food of the Wattled Crane is mainly aquatic eating the
tubers and
rhizomes of submerged sedges and
water lilies and also
insects,
snails and
amphibians.
Threats
Destruction, alteration, and degradation of wetland habitats constitute the most significant threats to the Wattled Crane. Hydroelectric power projects and other water development have caused fundamental changes in the species expansive
floodplain habitats, and their most important food source
Eleocharis spp. Human and
livestock disturbance, powerline collisions, mass aerial spraying of
tsetse flies, and illegal collection of
eggs, chicks and adults for food are also significant threats to Wattled Cranes throughout their
range.
The Wattled Crane is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. It is listed as Vulnerable in the IUCN Red List.
