Віреон зелений Vireolanius pulchellus

Chunky, sluggish green bird of humid evergreen forest in tropical foothills and lowlands. Rarely seen, but often heard singing monotonously from the canopy. Forages mainly at middle to upper levels, at times with mixed-species feeding flocks. Plumage is bright green overall, blending well with the foliage. Note the yellow throat and stout gray bill; turquoise-blue crown usually not visible from below. Similar Blue-crowned Chlorophonia has brighter yellow belly and stubbier bill.
