Variable Sunbird

Overview

The Variable Sunbird is aptly named for the considerable geographic variation in male plumage pattern across its broad sub-Saharan African range. It is a common visitor to gardens, savanna, forest edges, and cultivated land.

Males typically show an iridescent green or blue-green head, throat, and upper breast, with yellow underparts, though the exact extent and color of the iridescent patch differs among populations. Females are duller, generally olive above and pale yellow below.

Feather Identification

• Body feathers: Males show an iridescent green or blue-green throat and upper breast, with yellow lower underparts; the pattern and color intensity vary by population
• Female feathers: Olive-green above, pale yellowish below, lacking iridescence
• Tail feathers: Dark, slightly notched, without strong iridescence
• Shaft color: Dark in the iridescent throat patch, pale on yellow underparts
• Size: Small and slender, similar in size to other small African sunbirds
• Similar species: Because of its variable plumage across its range, this species can resemble several other sunbirds locally; best identified by combination of range, iridescent throat extent, and habitat

Plumage Details

Adult males show an iridescent green or blue-green throat and breast patch, varying in extent and exact hue among different populations, with yellow underparts below the iridescent area. Females are olive above and pale yellow below, lacking iridescent patches. Juveniles resemble females. Some populations show males with an eclipse-like duller phase, though this is less pronounced than in larger sunbird species.

Habitat & Range

Variable Sunbirds are widespread across sub-Saharan Africa, occurring from West Africa through East Africa and into parts of southern Africa, in gardens, savanna, woodland edge, and cultivated land. The species is largely resident, occupying a broad range of lowland and highland habitats depending on the region.

Behavior & Field Notes

This sunbird feeds on nectar from a wide range of flowering plants and shrubs, and also takes small insects, especially while feeding young. It builds a hanging, pouch-shaped nest, often suspended from a branch near human habitation. Calls include high-pitched chips and a rapid, twittering song delivered from exposed perches. The species' adaptability to varied habitats makes it one of the most commonly encountered sunbirds across much of its range.
