Central and eastern Africa from Gabon to Kenya in the north, and south to Angola and eastern South Africa.

[edit] Taxonomy

This is one of the many Sunbirds that have recently been moved to the genus Cinnyris from the genus Nectarinia.

Cinnyris bifasciatus has three subspecies which differ in the shade of the colour of their plumage, the width of the breast band, and bill length: Cinnyris bifasciatus bifasciatus from Gabon, Congo, Democratic Republic of Congo, Angola, Kenya, Uganda, Rwanda, Tanzania, Mozambique, Malawi, Namibia, Botswana, South Africa, and Swaziland; Cinnyris bifasciatus microrhynchus from Somalia, Kenya, and Tanzania; and Cinnyris bifasciatus strophium from Uganda, Tanzania, Zambia, Zimbabwe, and South Africa.

[edit] Habitat

Coastal bush, mangroves, forest edges and riverine forests and thicket.

[edit] Behaviour

Food includes nectar, insects and spiders. They are found singly or in pairs, except when birds (up to several hundred in some cases) aggregate at good nectar sources. These Sunbirds move restlessly between food sources, males constantly chasing both females and other males of their own species.
