The tropical boubou or bell shrike is a medium-sized passerine bird of sub-Saharan Africa. This very diverse "species" with its numerous subspecies and morphs has since long posed a taxonomic problem, and recent research suggests it is a cryptic species complex that has now been split into several species.
Region
East Africa
Typical Environment
Occurs widely in East Africa in a patchwork of habitats, especially dense scrub, secondary growth, thornbush, riverine vegetation, and woodland edges. It also uses coffee and tea estates, smallholder farms, and suburban gardens with substantial shrub cover. Generally avoids open grassland and the interior of tall, closed-canopy forests. Often stays low, moving through undergrowth and hedgerows. Pairs hold territories year-round and can be locally common where suitable cover exists.

Tropical boubous are famed for their rich, antiphonal duets in which the male and female sing precisely timed phrases that sound like a single bird. This species is part of a cryptic complex that has been split, with several look‑alike forms now treated as separate species. It is a shy skulker of dense thickets but readily reveals itself by voice. They occasionally mimic other birds and will approach softly when their duet is imitated.

Social Behavior
Typically encountered as pairs that maintain year-round territories. Both sexes perform coordinated duets and engage in mutual preening. Nests are small cups placed low to mid-level in dense shrubs; both parents defend the nest and feed the young. Breeding often coincides with local rains.
Migratory Pattern
Resident
Song Description
Rich, melodious whistles delivered as tightly synchronized male–female duets, often sounding like a single bird. Calls include sharp chucks and guttural notes; they may mimic other species. Duets carry well through dense vegetation, especially at dawn.
