About These Birds
Black-backed Water-tyrant
The Black-backed Water-tyrant is a small, attractive flycatcher of the riverbanks, lakeshores, and wetland margins of eastern Bolivia, southern Brazil, and northern Argentina. It has a white body with a bold black back and wings, and perches conspicuously on rocks and vegetation at the water's edge. It sallies out to catch insects over water.
