In some places, people cooperate with wild animals. These remarkable partnerships benefit the people and the animal, without domestication or captivity. For example, African honeyguide birds guide people to bees’ nests, allowing the people to harvest the honey and the honeyguide to eat scraps of beeswax. Dolphins in Brazil and Myanmar herd fish into fishers’ nets, and then eat those that escape. Historically,
hunters cooperated with wild animals, working with orcas to catch whales, and with wolves to catch bison.
In a world filled with human-wildlife conflict, how do these positive interactions between humans and wildlife work? To answer this, we brought together information about the diverse cases of ‘human-wildlife cooperation’.
We asked four questions:
How does human-wildlife cooperation function? We found that examples of human-wildlife cooperation known to science involve the animal finding or gathering food, and the human using tools to make it more accessible to both parties. In some cases, the human and animal communicate whilst cooperating, while in others they coordinate by watching each another.
How does human-wildlife cooperation develop? People learn how to cooperate with animals by watching their friends and relatives. In some cases, including the dolphins in Brazil, it is likely that the animals similarly “watch and learn” from each other (known as ‘social learning’). In other cases, including the honeyguides, some of the skills needed to cooperate with humans are instinctive. Whether the skills are
instinctive or develop by social learning affects how variable and vulnerable the interactions are.
How are the behaviours involved regulated? Little is known about the genes and hormones regulating animal cooperation with humans, but they may resemble those involved when animals cooperate with members of their own species.
How did human-wildlife cooperation evolve? Potential roots of human-wildlife cooperation include animals scavenging from humans, or humans using the presence of animals as a sign of nearby food. Over time, both parties could benefit by coordinating to achieve their common goal.
Many examples of human-wildlife cooperation are declining, and much remains to be learned before they are lost forever. Future studies will need to consider both the human and animal aspects of the interaction, so we can better understand the diversity of our current and ancestral interactions with the natural world.
