Distribution and habitat

Endemic to southern Africa, with the bulk of its population in west-central South Africa, extending into southern Namibia and Botswana. It is especially common in the shrublands of the Karoo and Kalahari.

Distribution of Rufous-eared warbler in southern Africa, based on statistical smoothing of the records from first SA Bird Atlas Project (© Animal Demography unit, University of Cape Town; smoothing by Birgit Erni and Francesca Little). Colours range from dark blue (most common) through to yellow (least common). See here for the latest distribution from the SABAP2.  

Food 

It mainly eats invertebrates supplemented with small fruit and seeds, often gleaning prey from the stems and leaves. The following food items have been recorded in its diet:

  • Invertebrates
  • Fruit
  • Seeds
    • Asparagus
    • Lycium (honey-thorns)
    • Atriplex semibaccata (Creeping saltbrush)

Breeding

  • The nest is an untidy oval shape with a side-top entrance, built of grey grass leaves and stems, or alternatively from strips of milkweed (Asclepias buchenaviana), reinforced with spider web and lined with plant down. It is typically placed up to 1 metre above ground in a bush or shrub, such as Driedoring (Rhigozum trichotomum), Doringvygie (Ruschia spinosa) and Bloubrakbossie (Galenia fruticosa).
  • Egg-laying season is year round, but it generally lays its eggs after rainfall.
  • It lays 2-7, usually 2-4 eggs, which are incubated for about 12-13 days.
  • The chicks are fed by both parents, leaving the nest after about 11-13 days.

Threats

Not threatened.
