Buphagus erythrorhynchus
Oxpeckers are part of the Starling family.
Male and female look the same. Juveniles have a black bill and lack the yellow ring around the eye.
Red-billed Oxpeckers nest in cavities in trees where between 2 and 5 eggs are laid.
Oxpeckers feed mainly on ticks and blood. While it would seem that it is beneficial to the mammal to have ticks taken off it, the Oxpeckers do have a habit of keeping wounds open.
These birds are found in woodland and savanna.
The Red-billed Oxpecker is a common sight in game reserves like Kruger National Park. They can be seen clambering around the backs, necks, heads and butts of larger mammals such as Burchell's Zebras, Giraffes and Impala. They are also found on cattle in some farming areas.
Two species of Oxpecker are found in South Africa and they are similar in looks. The Red-billed Oxpecker is far more common than the Yellow-billed Oxpecker. The Red-billed Oxpecker has yellow round its eye and a completely red bill.
