The Ruby-cheeked Sunbird has different male and female plumage. It forages high in trees, taking nectar from flowers and sometimes insects from spider webs.
Males have iridescent green-blue upperparts, coppery ear-coverts, and orange-rufous on the chin and upper breast. Females have olive-green upperparts and yellow underparts.
It forages in the canopy and upper storey, probing flowers for nectar and sometimes visiting spider webs for insects.
