 For example, some species of hornbills in Africa have a mutualistic relationship with dwarf mongooses, foraging together and warning each other of nearby birds of prey and other predators.Other relationships are commensal, for example following monkeys or other animals and eating the insects flushed up by them.The family Bucerotidae was introduced (as Buceronia) by the French polymath Constantine Samuel Rafinesque in 1815.
