̽»¨Ö±²¥tale of two charismatic species cooperating for mutual benefit has captivated naturalists for centuries – but evidence has been patchy. Researchers have now carried out the first large-scale search for evidence.
By following honeyguides, a species of bird, people in Africa are able to locate bees’ nests to harvest honey.  Research now reveals that humans use special calls to solicit the help of honeyguides and that honeyguides actively recruit appropriate human partners. This relationship is a rare example of cooperation between humans and free-living animals.
Newly hatched chicks of African honeyguide birds bite to death their foster siblings to eliminate competition.
