Карликовый виреон Vireo nelsoni

Small, relatively active vireo of scrubby woodlands and brushy thickets in highlands; mainly in areas of oak woodland. Endemic to southwestern Mexico. Tends to forage low and alone, usually not with mixed-species flocks. Overall plumage and even its short, dry chatter remarkably similar to Ruby-crowned Kinglet, a winter migrant in the range of Dwarf Vireo. Note the vireo’s whitish spectacles, amber eyes, two distinct whitish wingbars, stouter bill, and stouter gray legs relative to a kinglet. Cap is paler and less contrasting than cap of similar female Black-capped Vireo. Also compare with similar Hutton’s Vireo.
