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.

Bay-ringed Tyrannulet

The Bay-ringed Tyrannulet is a small flycatcher of the Atlantic Forest in southeastern Brazil and northeastern Argentina. It has a brownish-olive plumage with faint wing bars and a subtle eye ring. It forages actively in forest canopy and edges, gleaning insects from foliage.
