Distribution and habitat

Endemic to southern Africa, with the bulk of its population in the Western Cape, Eastern Cape, KwaZulu-Natal, Lesotho, Swaziland and Lempopo Province; it also occurs in Zimbabwe’s eastern highlands. It generally prefers habitats with restios, rank grasses or ferns, such as fynbos and grassland. It also occupies montane forest edges with Bracken (Pteridium aqualinum) and Brier (Smilax anceps).

Distribution of Cape grassbird 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 insects, such as beetles, grasshoppers and caterpillars, doing most of its foraging on the ground beneath vegetation.

Breeding

  • The female builds the nest, which is a bowl built of twigs, grass blades, leaves, lined with finer plant material. It is typically concealed near the ground in a tussock of grass or Restio, or just in some tangled vegetation.
  • Egg-laying season is from about July-December in the Western Cape, elsewhere it is from roughly October-April, peaking from October-December.
  • It lays 2-3 eggs, which are incubated solely by the female for approximately 14-18 days.
  • The chicks are fed by both adults, leaving the nest after about 14-16 days.

Threats

Not threatened.
