Includes Ethiopian Boubou^[2]

[edit] Identification

23 to 25 cm

• Glossy blue-black upperparts and tail
• White spots on the rump
• White underparts with buffy or pink tinge on the breast and flanks
• Black bill
• Dark reddish-brown eyes
  

• The wings have white markings that vary, depending on subspecies
• There is an all-black morph in a small area of coastal Kenya
  

Juveniles: similar but duller

• Grey-brown bill
• Upperparts mottled by yellowish-ochre to tawny feather tips
• Dusky-barred flanks

[edit] Distribution

Sub-Saharan Africa, as far south as 25ºS.

[edit] Taxonomy

There are five subspecies:^[1]

• L. a. major

• Sierra Leone to southern Sudan, Kenya, Tanzania and Malawi

• L. a. aethiopicus

• Extreme eastern Sudan to Eritrea, Ethiopia, Somalia and northern Kenya
• Split by Gill and Donsker (2010)^[2] as Ethiopian Boubou

• L. a. ambiguus

• Kenya and north-eastern Tanzania

• 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

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.

[edit] 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.

[edit] Behaviour

[edit] 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.

[edit] 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.
