Distribution and habitat

Occurs from Cameroon and the DRC to southern Africa, where it is locally common in northern Botswana, the Caprivi Strip and the upper-most reaches of Namibia. It almost only occurs along watercourses with surrounding dense vegetetation, such as tall reedbeds, Cyperus papyrus (Papyrus) and Ficus verruculosa (Water figs).

Distribution of Swamp boubou 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).

Food 

It eats a variety of insects, fruit and rarely frogs, doing most of its foraging in reedbeds or trees, gleaning prey from the vegetation. It also forages on the ground, flicking plant detritus around with its bill in a manner similar to thrushes (Muscicapidae).

Breeding

  • The nest is a shallow cup of woven twigs and rootlets, usually placed in small thicket or bush about 2-3 metres above ground.
  • Egg-laying season is almost year round, usually peaking around November.
  • It lays about 2 eggs which are incubated by both sexes, singing a duet whenever they change shifts.

Threats

Not threatened.
