The olive sunbird is a species of sunbird found in a large part of Africa south of the Sahel. It prefers forested regions, and is absent from drier, more open regions such as the Horn of Africa and most of south-central and south-western Africa. It is sometimes placed in the genus Nectarinia.
Region
Sub-Saharan African forest belt
Typical Environment
Occurs widely in humid forests and forest edges from West Africa through Central Africa to parts of East and southeastern Africa. It favors primary and mature secondary lowland forest, gallery forest, and wooded plantations, and readily visits shaded gardens near forest. The species is scarce or absent in drier, more open regions, including much of the Sahel, the Horn of Africa, and arid zones of south-central and southwestern Africa. It often stays within dense foliage from the understory to mid-canopy, occasionally venturing into the canopy when flowering trees are in bloom.

The olive sunbird is a mostly forest-dwelling sunbird that acts as an important pollinator while also gleaning small arthropods. Some authorities split it into Eastern and Western olive sunbirds based on vocal and genetic differences. It is often inconspicuous compared to more iridescent sunbirds, relying on rapid, high-pitched calls and a swift, darting flight.

Social Behavior
Usually found singly or in pairs, sometimes in loose associations where flowers are abundant. Pairs defend rich nectar sources and suitable nesting sites. The nest is a suspended, purse-like structure woven from plant fibers, moss, and spider webs; the female does most of the construction and incubation. Breeding timing varies regionally with rainfall and flower availability.
Migratory Pattern
Resident
Song Description
Song is a rapid, high-pitched series of tinkling and twittering notes delivered from concealed perches. Calls include sharp tsip and thin seee notes, often repeated in quick succession.
