New paper on human-honeyguide cooperation and communication

A new study from the Honeyguide Research Project shows that Greater Honeyguides learn the distinct calls that honey-hunters in different parts of Africa use to communicate with them, facilitating cooperation between species. Greater Honeyguides are wax-eating African birds that lead people to bees’ nests, so that we humans can open the nest using fire and tools, revealing honey for us and wax for the bird. To attract honeyguides and to coordinate a cooperative honey-hunt, human honey-hunters signal to honeyguides using specialised calls that vary culturally across Africa, from trills, grunts and words, to different types of whistles. The new study shows using field experiments in Mozambique and Tanzania that honeyguides learn and prefer the specialised calls of the local human culture they interact with, compared to those of a foreign culture. This implies that honeyguides can adjust to human cultural diversity, increasing the benefits of cooperation for both people and birds: effective communication between species makes honeyguides more likely to interact with a cooperative human (and so get more wax), and humans more likely to interact with a cooperative honeyguide (and so get more honey). It also suggests that communication between humans and other species can assign meaning to arbitrary sounds in a similar manner to human language.

Laltaika carrying out field experiments in Tanzania

Eliupendo Laltaika is hard at work with his field experiments in southern Tanzania, assisted by Ndorobo honey-hunters Mboyo Lemoho and Lelia Olapi, and currently hosted by the beekeeping community of Mwamagembe village in the Rungwa region. Laltaika’s experiments at a range of site in southern Tanzania aim to find out how learning hones honeyguides’ understanding of different human sounds.
