[edit] Similar Species

Resembles the Southern Fiscal but has shorter tail and the white wing stripe extends to the secondaries. It also behaves quite differently. The Boubou is a skulker in low vegetation while the Fiscal tends to perch up in the open. Distinguished from Tropical Boubou and Swamp Boubou by its rufous flanks, undertail and belly.

[edit] Distribution

Southern and eastern South Africa, Swaziland and southern Mozambique.

[edit] Taxonomy

[edit] Subspecies

Laniarius ferrugineus has 6 subspecies[1]. These vary in size and plumage colouration.

  • L. f. ferrugineus from south-western South Africa (west of 23° 20' E) is described above;
  • L. f. natalensis from the interior of south-eastern South Africa south of 27° 30' S; the male has a whiter throat and breast than the nominate race and the female has darker upper parts;
  • L. f. pondoensis from coastal south-eastern South Africa (24° 20' E to 29° 20' S); the upper parts of the male are more glossy than those of the nominate race, and the under parts are slightly olive;
  • L. f. transvaalensis from north-eastern South Africa and Swaziland; breast buffy white and belly paler rufous than nominate;
  • L. f. tongensis Mozambique south of 20° 20' S and south to St Lucia in South Africa; most of under parts white; flanks and belly buffy; smaller than nominate;
  • L. f. savensis Mozambique north of 20° 20' S and south of Save River; similar to L. f. tongensis, but smaller with slate grey upper parts.

[edit] Habitat

Forest, forest edge, thickets and well-wooded gardens.

[edit] Behaviour

Generally secretive and most easily found by following the call, but does become habituated to humans at picnic sites and in gardens. Responds to spishing.

[edit] Diet

Usually keeps to thick vegetation, where it forages mainly for invertebrates, eggs and nestlings, but also fruit and seeds.

[edit] Breeding

The nest is a shallow cup of sticks, roots, grass and spider web, usually concealed in dense vegetation. Two to three eggs are laid August to February.

[edit] Vocalisation

The Southern Boubou has a large repertoire of calls including loud ringing notes and harsh buzzing sounds. Often calls in duet, birds alternating several times.
