The African barbets are birds in the family Lybiidae. They were usually united with their New World and Asian relatives in the Capitonidae for quite some time, but this has been confirmed to be limited to the main New World lineage. There are 42 species ranging from the type genus Lybius of forest interior to the tinkerbirds (Pogoniulus) of forest and scrubland. They are found throughout sub-Saharan Africa, with the exception of the far south-west of South Africa.
The African terrestrial barbets, Trachyphoninae, range from the southern Sahara to South Africa. Members of one genus, Trachyphonus, they are the most open-country species of barbets. The subfamily Lybiinae contains the African arboreal barbets. There are 36 species of Lybiinae in 6 genera.
Most African barbets are about 20–25 cm (7.9–9.8 in) long, plump-looking, with large heads, and their heavy bill is fringed with bristles; the tinkerbirds are smaller, ranging down to the red-rumped tinkerbird (Pogoniulus atroflavus) at 7 g (0.25 oz) and 9 cm (3.5 in).
They are mainly solitary birds, eating insects and fruit. Figs and numerous other species of fruiting tree and bush are visited, an individual barbet may feed on as many as 60 different species in its range. They will also visit plantations and take cultivated fruit and vegetables. Fruit is eaten whole and indigestible material such as seed pits regurgitated later (often before singing). Regurgitation does not usually happen in the nest (as happens with toucans), although tinkerbirds do place sticky mistletoe seeds around the entrances of their nests, possibly to deter predators. As the other barbets, they are thought to be important agents in seed dispersal in tropical forests.
