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.
Alder Flycatcher
The Alder Flycatcher is a small North American flycatcher weighing about 13 g with a wingspan near 14 cm. It breeds in alder thickets and wet scrub across Canada and the northern United States, identified primarily by its distinctive fee-BEE-o song rather than its plain olive-grey plumage.
