Black-billed Shrike-tyrant
The Black-billed Shrike-tyrant is a large, ground-hunting tyrant flycatcher of open Andean habitats in Argentina, Bolivia, Chile, and Peru, with grey-brown upperparts, a whitish throat, and a stout dark bill. It inhabits open puna grasslands, rocky slopes, and high-altitude shrubby areas. It feeds on insects, lizards, and small rodents, hunting prey on the ground from exposed perches.
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.
