The White-tailed Tyrannulet is a small flycatcher of montane forest in northwestern South America.  Found from Colombia south to Peru, the species prefers Andean forest canopy between 1500 and 2500 meters in elevation.  In appearance, it is olive above and gray below with a gray head marked by a white supercilium, black wings with two bright yellow covert bars and secondary edges, and a short, grayish tail with two primarily white outer tail feathers on each side.  White-tailed Tyrannulet is often found foraging in mixed flocks and can be easily detected by its mournful, descending series of four "peer" notes.
