About These Birds
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.
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.
