Small, very drab grayish-brown flycatcher. Widespread from Costa Rica through much of South America. Relatively lanky, with long tail. Looks most similar to an oversized beardless-tyrannulet or a small elaenia. Usually shows brownish wingbars, pale eyebrow, and pale yellow belly. Listen for “pip” calls followed by a sputtering buzzy chatter, or a slow buzzy trill. Different populations might represent separate species. Generally occurs in scrubby habitats and edges, sometimes following mixed-species flocks.
