Lybiidae – African Barbets
The Lybiidae or African barbets are a family of near passerine birds confined to Africa. They were usually united with their American and Asian relatives in the Capitonidae for quite some time. The species range 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.
Most African barbets are about 20cm to 25cm 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 at 7g and 9cm. 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.
As well as taking fruit, African barbets also take arthropod prey, gleaned from the branches and trunks of trees. A wide range of insects are taken, including ants, cicadas, dragonflies, crickets, locusts, beetles, moths and mantids. Scorpions and centipedes are also taken, and a few species will take small vertebrates such as lizards, frogs and geckos.
The precise nesting details of many African barbets are not yet known, although peculiarly among the Piciformes, some sociable species will nest in riverbanks or termite nests. Like many members of their order, Piciformes, their nests are in holes bored into a tree, and they usually lay between 2 and 4 eggs (except for the Yellow-breasted Barbet which lays up to 6), incubated for 13 to 15 days. Nesting duties are shared by both parents.

Bearded Barbet Lybius dubiusSpecies AccountThe bearded barbet (Lybius dubius) is an African barbet. Barbets and toucans are a group of near passerine birds with a worldwide tropical distribution. The barbets get their name from the bristles which fringe their heavy bills.
