Identification

How to recognise it

Extremely similar to Fülleborn's Black Boubou (sometimes considered the same species) but with a different call, range and immature plumage. The female and immature are slightly duller, without Fülleborn's olive-green wash.

Calls & Song

What it sounds like

An exceptionally wide variety of antiphonal calls and whistles, possibly unmatched by any other Laniarius — often sequences of bell notes followed by an explosive "tchank".

Distribution

Where you'll find it

Common but restricted to highland forest in the west, calling frequently but hard to locate in the dense undergrowth and tangled creepers of the Albertine Rift. In the Rwenzori it is found above 2,200 m — from the lunch point on the Enock's Falls trail up to the bamboo zone above Sine Camp, above the lunch point toward Samalela, and the whole trail to Kihalo Camp at 3,490 m.

Behaviour — Feeding

Diet

Eats various insects — beetles, grasshoppers and caterpillars — and occasionally snails, isopods and crustaceans.

Breeding & Nesting

Nesting

Breeding is little known; the season runs November–January and March (with breeding condition October and April) in South Uganda.

Movement & Local Notes

On the trail

A resident, heard all year along the trails, but it can make a vertical migration below its usual altitude depending on food. Not a threatened species.
