The black crowned-crane (Balearica pavonia) is an International Union for Conservation of Nature (IUCN) Red List “Vulnerable” species found across sub-Saharan Africa, from Guinea to Ethiopia. Scientists recognize two distinct subspecies between the east and west parts of its range. Both subspecies are found primarily in wetlands areas of savanna habitats. Freshwater marshes, wet grasslands, and larger bodies of water provide breeding habitat for the cranes. Breeding pairs build their nests from grasses in and around wetlands.
Besides being the national bird of Nigeria, black crowned-cranes are a culturally important animal to many people. This role contributes to some of the challenges it faces. Adults and eggs are hunted by subsistence hunters and traders and are also sometimes used in traditional medicines.
Habitat loss plays a critical role in the species’ survival. The crane’s habitat is under stress from both human and natural causes. Drought and bushfires are common, and agricultural activities such as overgrazing, wetlands conversion, and logging occur throughout its range.
Most populations of black crowned-cranes appear to be declining in number, but regional conflicts have made it unsafe for scientists to conduct detailed count surveys. In most countries, the crane is legally protected. Guinea has suspended international trade of the species, but export continues in other parts of its range, especially Sudan, where continued tension makes enforcement of bans difficult.
