The small Mistletoebird is the only Australian representative of the flowerpecker family, Dicaeidae, and is also known as the Australian Flowerpecker. Males have a glossy blue-black head, wings and upperparts, a bright red throat and chest, a white belly with a central dark streak and a bright red undertail. Females are grey above, white below, with a grey streak on the belly, and a paler red undertail. Young birds resemble females but are paler and have an orange, rather than dark, bill. These birds are swift and erratic fliers, moving singly or in pairs, usually high in or above the canopy.
