bell-shrike

Bell-shrikes, also known as bellbirds, are African birds belonging to the genus Laniarius within the bush-shrike group. These birds are approximately 20 cm (8 inches) long and are typically plain-coloured, often with a white wing slash. Some species are entirely black, like the sooty boubou (L. leucorhynchus), while others are black and white with reddish underparts, such as the tropical boubou (L. aethiopicus). Other examples include the black-headed gonolek (L. erythrogaster) and the Barbary shrike (L. barbarus), which are black above and bright red below. These birds are named for their ringing voices, with names like "boubou" and "gonolek" often imitating the males' calls.12
