African yellow white-eyes breed in August-January, with a peak in September-October. The nest is a small cup built of dried grass and small twigs, secured with spider web. It is typically placed in the foliage of a sapling, often about 3-5 m above ground in the shade. There the female lays 2-4 eggs, which are incubated by both parents for about 11-12 days. The chicks are cared for by both parents, fledging 13-14 days after hatching.

This species has an extremely large breeding range and is described as common. The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
