Tropical Boubou

Overview

The Laniarius major, also known as the tropical boubou or bell shrike, is a medium-sized passerine bird native to sub-Saharan Africa that forms part of a complex of related species. It is characterised by its large size for a bushshrike, measuring 23–25 cm in length, and is notable for being heard more often than it is seen.

Identification

• Glossy blue-black upperparts and tail with concealed white rump spots visible when the wings are spread.
• White underparts, often with a buffy or pinkish tinge on the breast and flanks.
• Black bill with a length of 20–25 mm, and bluish-grey legs and feet.
• Dark reddish-brown irises, with no distinct sexual dimorphism in size or plumage.

Habitat

This species ranges from approximately 10°N latitude south to the Limpopo River in South Africa, excluding the inner Congo Basin and parts of the Atlantic coast. It prefers habitats with dense ground cover, including savannah, Miombo woodland, forest edges, and village gardens, while avoiding arid regions and dense equatorial rainforests. It is a sedentary bird that does not migrate but may make seasonal movements in some areas, such as Kenya.

Diet

The tropical boubou forages on or near the ground and feeds on a variety of large terrestrial invertebrates, such as beetles, orthopterans, and termites, as well as small vertebrates including frogs, geckos, lizards, rodents, and snakes. It is a carnivorous eater that impales large prey on thorns or wedges it into crevices to consume later. It also plunders other birds' nests and occasionally consumes snails and fruit.

Did you know?

This species produces a complex series of duets that function like a Morse code, with males and females exchanging notes in rapid sequence, sometimes involving up to 75 repetitions. It can duet with other species, such as the slate-colored boubou, and its calls include loud "bou" or "boubou" sounds that give the bird its name.
