Orange River White-eyes occur only in South Africa’s central and western provinces and into Namibia, where they commonly inhabit thorny riparian vegetation and well-planted gardens, feeding primarily on insects and other invertebrates. Little is known about the breeding habits of these tiny birds (9g in weight, 11cm long), though their nesting season apparently spans spring and summer.
The IUCN considers the Orange River White-eye to be of least concern. Many authorities consider it a subspecies of the closely related and very similar Cape White-eye, with which it sometimes interbreeds. We had our first encounter with the Orange River White-eye during a recent visit to Augrabies Falls National Park.
