The white-breasted cormorant (Phalacrocorax lucidus) is distinguished from other forms of the great cormorant by its white breast that is sharply separated from its black upper-parts – and by the fact that subpopulations are freshwater birds. The white-breasted cormorant is the only form of great cormorant found in Sub-Saharan Africa, the only form that has strictly freshwater populations and the only form with a white breast and throat. It does interbreed freely with dark-breasted forms in central Africa.
