Large but rather plain and often local flycatcher of semiopen and open scrubby habitats in drier regions of the Andes and Patagonia. Perches prominently atop bushes, trees, and wires. Runs well on ground, chasing down small lizards and other prey. Distinguished by overall drab plumage with grayish belly and vent, blackish tail, and stout bill. Compare with Great Shrike-Tyrant, which has limited range overlap.
