Ethiopian boubou, Laniarius (aethiopicus) aethiopicus, also known as the boubou shrike, tropical boubou or the bell shrike is member of the bushshrike family, Malaconotidae. Lanarius are carnivorous songbirds commonly known as boubous or gonoleks. They were formerly included with the true shrikes in the family Laniidae, but Lanarius and related genera were separated into the bush-shrike family.
The Ethiopian boubou was formerly classified into a species complex as a subspecies along with five other birds that look very similar, but most of which are apparently are not that closely related. These birds were all known as tropical boubous. The Ethiopian boubou was recently split from these five taxa into its own species (it's likely that at least two more of its sister subspecies will soon be elevated to full species status based on DNA work).
The Ethiopian boubou's other common name, the bell shrike, is in honour of its courtship song, a duet that both the male and female sing. This song has a clear bell-like call, consisting of a male and female singing alternate notes, producing a song that sounds like the creation of one bird.
