Overview

Overview

The Copper Sunbird is found across a broad swath of sub-Saharan Africa, from savanna woodland to forest edges and gardens. Males appear nearly black in poor light but reveal rich coppery-purple and bronze-green iridescence when sunlight catches their feathers directly. Females are plain and yellow-bellied, making the sexes easy to tell apart.

  • Family: sunbirds (Nectariniidae)
  • Diet: nectar and small insects
  • Range: sub-Saharan Africa, widely distributed

Identifying the Feather

Feather Identification

  • Overall color: male body feathers appear blackish in shade but flash coppery-purple, bronze, and green iridescence in direct light.
  • Head: crown and throat show the strongest metallic sheen, often with a purplish cast.
  • Underparts: belly feathers in males are dark, without the yellow seen in females.
  • Flight feathers: wings and tail are dull blackish-brown, non-iridescent.
  • Vs. similar species: the overall dark, coppery iridescent male plumage without a contrasting bright chest band helps separate it from double-collared sunbirds.

Plumage & Molt

Plumage Notes

Adult males show glossy dark coppery-purple to bronze-green plumage year-round, brightest when feathers are fresh after molt. Females are olive-brown above and pale yellow below, entirely lacking iridescence. Juveniles resemble females until males molt into full adult coloration.

Habitat & Range

Habitat & Range

The Copper Sunbird occupies savanna woodland, forest edge, riverine growth, and gardens across a wide range of sub-Saharan Africa, from West Africa through the Congo Basin to parts of East Africa. It is largely resident with some local seasonal movements tied to flowering.

Behavior & Field Notes

Behavior

This sunbird feeds on nectar from a variety of flowering trees and shrubs, supplementing its diet with small insects and spiders. It builds a small pouch nest suspended from a branch. The song is a simple, high-pitched warbling, and calls include sharp chips given during feeding disputes.
