The wattled crane (Grus carunculata) is a large, threatened species of crane found in wetlands and grasslands of eastern and southern Africa, ranging from Ethiopia to South Africa. Some authorities consider it the sole member of the genus Bugeranus.
The wattled crane occurs in eleven countries in eastern and southern Africa, including an isolated population in the Ethiopia Highlands. More than half of the world's wattled cranes occur in Zambia, but the single largest concentration occurs in the Okavango Delta of Botswana.
The wattled crane has been spotted in Uganda for the first time in 2011, seen in the Kibimba Rice region in the eastern side of the country. This sighting brings the total number of bird species in Uganda to 1040.
In April 2018, a new population of Wattled Cranes was discovered in Angola.
Wattled cranes inhabit fairly inaccessible wetlands under most conditions. It requires shallow marsh-like habitats with a good deal of sedge-based vegetation. 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. It is one of the more herbivorous of extant cranes. The other primary portion of the diet consists of aquatic insects. They will supplement the diet with snails, amphibians and snakes when the opportunity arises. Roughly 90% of foraging done by this species occurs in shallow waters. They typically forage by digging vigorously with their bill into the muddy soil. On occasion, it will eat grain and grass seed as well, but does so much less often than the other three African crane species.
There does seem to be some seasonal movements in this crane species, but they are not well-known. Movements seem to be dictated by local water conditions rather than by seasonal temperature variations. During local floods, the number of wattled cranes can increase from almost none to as much as 3,000 individuals.
These movements, in pursuit of ideal feeding conditions, seem more opportunistic movement rather than a fixed migration pattern. On the other hand, there has been observed a migration movement from the high to the low plateaus in Mozambique for the species.
