Distribution and habitat

It occurs from Tanzania to Mozambique, Zimbabwe, South Africa and the Caprivi Strip. It is fairly common in southern Africa, preferring dense areas of undergrowth in broad-leaved woodland with miombo (Brachystegia) and Zambezi teak (Baikiaea plurijuga). It also occupies Acacia woodland, and it may even move into suburban gardens in Zimbabwe.

Distribution of Stierling's wren-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 insects, doing most of its foraging in the foliage of trees and bushes, gleaning prey from leaves and stems.

Breeding

  • The nest is ball-shaped with a side entrance, made of fine grass, felted plant down and secured with spider web to the surrounding foliage. It is typically placed in the mid canopy of a broad-leaved tree, such as Msasa (Brachystegia spiciformis), Buffalo-thorn (Ziziphus mucronata) and Velvet bushwillow (Combretum molle).
  • Egg-laying season is from September-March, peaking from October-December.
  • It lays 2-4 white to light blue eggs, covered with tiny reddish brown dots.
