A yellowish canopy-dweller with a long, powerful-looking bill. Male is dark above and yellow below, while female is ironically distinctive in her lack of distinctive characteristics; she is plain gray-green above and yellow below. Both sexes can be separated from other ioras by their proportionally larger billa, greater size, and lack of wingbars. Inhabits primary and late secondary broadleaf forests, as well as forest edge, in lowland and foothill regions. Song is a rapid-fire series of high-pitched “chew” notes. Like other ioras, frequently joins mixed-species flocks.
