An inconspicuous, relatively tame, medium-sized flycatcher of woodlands and tall scrub. Typically perches motionless below the canopy of the tree before sallying forth in pursuit of prey. Distinguished from similar species within its range by combination of gray chest, yellow belly, and rust-brown undertail. Often first detected by its plaintive, drawn out “pheee” or “pheeuuu” song. Also makes a variety of “pip” and rolling trill calls.
