Although common residents of humid and wet forests, Purple-bibbed Whitetips are difficult to see since they rarely forage out in the open. They typically forage by themselves, taking nectar from small flowers or hovering as they glean for insects. Purple-billed Whitetips build their nests of moss and ferns in shrubs or vines along steep ravines. Both males and females have a large white spot behind the eye and the white bottom half of the male's central tail feathers creates the appearance of a large white tail spot. Females are green above and white below with extensive green spotting.
