Distribution
Sub-Saharan Africa, as far south as 25ºS.
Taxonomy
There are four subspecies:[1]
- L. a. major
- Sierra Leone to southern South Sudan, Kenya, Tanzania and Malawi
- L. a. ambiguus
- L. a. limpopoensis
- Eastern Botswana, southern Zimbabwe, northern South Africa, and adjacent extreme western Mozambique
- L. a. mossambicus
- North-eastern Botswana to southern Zambia, Malawi and Mozambique
Formerly considered conspecific with Ethiopian Boubou under the scientific name Laniarius aethiopicus .
Molecular sequence data indicate that Somali Boubou and Zanzibar Boubou are separate species.3 Furthermore Bulo Burti Boubou has been shown to be synonymous with Somali Boubou.
Habitat
Forest and forest-edge, savanna woodland. In the drier parts of its range, the only suitable habitat is riparian forest. Also found in gardens and thickets.
Behaviour
Diet
The diet includes large insects, arthropods, small mammals, reptiles, and amphibians. It robs nests for the eggs and occasionally eats snails and fruit. They hold large prey down with the foot whilst eating. Like other bush-shrikes, it impales prey on thorns to eat later.
Breeding
Both sexes build the cup shaped nest of twigs, tendrils, and small roots held together with spider web, but the female does more of the work. The clutch consists of 2-3 bluish to buffy green eggs with brown and lilac spots. They are incubated by both adults for about 15 days. Nestlings fledge after a similar period. Both sexes feed the young.
