A medium-sized canopy-dweller of lowland and foothill forests, often seen with mixed flocks. Male is dark olive-green with boldly black-and-white-striped wings; female is paler, with an olive back and a less contrasting wing pattern. Look for bright yellow “goggles” around dark eyes in both sexes; Common Iora lacks these goggles and has pale eyes, but these can be hard to discern. Song is high, simple, and repetitive: “wit-dee, wit-dee, wit-dee” or “chew-a-wee-chew, chew-a-wee.” Calls vary, but the most common ones are downslurred and rather nasal-sounding.
