The crested barbet (Trachyphonus vaillantii) is a sub-Saharan bird in the Lybiidae family. Its specific name commemorates François Levaillant, a famed French naturalist.
With its thick bill and very colourful plumage the crested barbet is unmistakable. This small bird has a speckled yellow and red face with a small black crest. The belly is yellow with red speckles, wings are black with white specks and it has a broad black band on its neck. Yellow head and body with black and white feathers, red markings on end of body, its colour blends well in the bush. They have a distinct shrill.
They are found singly or in pairs. They like to bounce around on the ground looking for food, they usually call from a branch out in the open. They do not fly easily and then only for short distances. Crested barbets roost in holes in trees. They are very vocal, the call being a trill that can continue for long periods. Crested barbets are aggressive towards other birds in their territory and chase off both nest competitors such as other barbets and other birds such as doves and thrushes. They have also been recorded to have attacked rats and killed snakes.
