Imitator Sparrowhawk

A tiny, rotund flycatcher found singly in the understory of montane forest from Panama to Peru. Very nondescript plumage: darker olive above with a dull tawny breast and yellowish belly. Looks uniformly brownish in bad light. Usually stays low, where it perches quietly and sallies out to glean insects. Often detected by its snapping sounds and whirring wingbeats. Occurs from around 700–2,000 m, typically lower than Rufous-headed Pygmy-Tyrant but some elevation overlap.

A medium-sized warbler of moist montane dwarf forests where it feeds actively in dense canopy foliage. It is most readily distinguished from Black-and-white Warbler by the absence of white streaking on its back and the lack of a white eyebrow. Easily separated from Blackpoll Warblers, which have a white, not black cheek. Song is a thin trill, higher pitched during first half and lower pitched during the second. Call note is a high, thin “Peet.”

Small sleek tanager with distinctive color pattern: pale sandy underparts with peachy blush on breast, black mask, powdery-blue crown, and darker blue back and wings. Sexes alike. Uncommon in second growth, edges, and gardens, where it is most often seen singly or in pairs. Occasionally follows mixed-species flocks. Found from foothills to upper subtropical zone in Andes, sometimes straying even higher. Populations in southeastern South America occur at lower elevations.
