Choco Vireo Vireo masteri

Rare vireo found only in lush Andean cloud forest in northwestern Ecuador and western Colombia. In contrast to the much more common Brown-capped Vireo, it has pale wingbars and may show an ochraceous wash on the throat and breast. Often accompanies mixed-species flocks high in the canopy, where it can be hard to see well. Song is a quick series of sweet-sounding notes that vary in pitch unpredictably.
