Oxpecker, or Buphagus africanus, is a unique bird that specializes in feeding on parasites and ticks that live on large African mammals such as buffaloes, giraffes, and rhinoceroses. While it has a unique name, there are several synonyms used to describe the bird, such as tickbird, buffalo bird, and rhinoceros bird. Additionally, the oxpecker is known in Swahili as "askari wa kifaru" meaning the "rhinoceros' guard". These synonyms help to describe the oxpecker's important role in the ecosystem by keeping large mammals free of parasites, and its unique physical features such as its sharp, curved beak and feather coloration.
