Habitat: Red-billed oxpeckers live in open savannas, bushlands, and forests (up to elevations of 9,000 feet (2,745 meters) that contain large mammals including domestic livestock.


Diet: The birds feed on parasites (organism living on another) such as ticks, fleas, and other biting flies taken from host mammals and on host blood and dead tissues and skin. They can eat hundreds of these parasites each day.


Behavior and reproduction: Red-billed oxpeckers remain in the same area and do not migrate. They live alongside large mammals and are often found perching (sitting) on the heads and necks of rhinoceros, elephants, giraffes, and cape buffaloes. Courtship often takes place on the backs of these host mammals. Breeding occurs at different times in different areas, often at the beginning of the rainy season but has been reported in all months. They build nests in natural tree cavities made of grasses lined with hair and dung. Females lay one to five creamy white eggs with brown to lilac speckles. The incubation period is twelve to thirteen days, and is done by both parents. Both parents and helpers feed the young. The fledgling period is about thirty days, but remain dependent on the parents for another thirty days.

Red-billed oxpeckers and people: People often consider red-billed oxpeckers as pests, especially around livestock. Extermination programs have been carried out in various agricultural areas to kill off the birds.
