Red-billed Tyrannulet Zimmerius cinereicapilla

Small and rather scarce flycatcher found in disturbed forest on the east slope of the Andes. Yellowish-olive with a gray head and pale throat. Combination of stubby, reddish bill, pale iris, and yellow edges to wing feathers that do not form distinct wingbars help separate it from other small flycatchers. Overlaps with the very similar Mishana Tyrannulet in northern Peru, but Red-billed has a gray (not olive) crown and a different voice. Calls include soft whistles and squeaks, given alone or in a quick series. Typically seen perched high in a tree in a clearing or at forest edge.
