About These Birds
Acadian Flycatcher
The Acadian Flycatcher weighs about 13g and breeds in eastern North American forest ravines. It is identified by its sharp 'peet-sa' call and olive-green upperparts.
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.
