A medium-sized flycatcher that sticks to the understory in lowland and foothill forest from Panama to the Amazon basin of Brazil and Peru. Brown above and pale whitish-yellow below. Overall rather nondescript, but look for brighter rusty edging on the wing feathers and tail and a pale brownish eye. Regularly raises wings up while perched. Namesake twisted outer primaries are difficult to see. Most easily identified by voice, a loud, fairly low-pitched “teew!”
