Wild Animals That Form Survival Partnerships With Completely Different Species

Oxpeckers are frequently photographed riding on rhinoceroses, giraffes, buffalo, zebras, and other large African mammals, creating one of the continent’s most recognizable interspecies associations. The birds feed on ticks and other material found on their hosts’ bodies, gaining access to a mobile feeding ground that can provide a steady source of food. The mammals may benefit from the removal of some ectoparasites, although scientists caution that the relationship is more complicated than the familiar textbook version suggests. Oxpeckers also consume blood and can peck at existing wounds, meaning their behavior can sometimes shift toward parasitism rather than straightforward mutualism. More recent research has revealed another potentially important service: oxpeckers can function as an early-warning system, with black rhinoceroses responding to their alarm calls when humans approach. This makes the association particularly interesting because its benefits may include surveillance as well as grooming.
