Great Shrike-Tyrant Agriornis lividus

Large but rather plain flycatcher of semiopen and open scrubby habitats, matorral, lighter woodlands, and hedges in drier farmland of lowlands and foothills. Generally scarce and local. Perches prominently atop cacti, bushes, and wires. Runs well on the ground, chasing down small lizards and other prey. Distinguished by overall drab plumage with pale rusty vent, blackish tail, and stout bill. Most likely to be mistaken for Austral Thrush, which is similar in size and plumage tones, but has a bright yellow bill.
