We are delighted to have a new paper on wax-eating behaviour by honeyguides and other animals published in Proceedings of the Royal Society B. In this study we used camera traps to investigate which animals, other than honeyguides, fed on wax made available from the human-honeyguide mutualism, and whether larger animals feeding on this unusual food undermined the mutualism by depriving the honeyguide of its reward. Our camera trapping revealed nine wax-eating species, five of which were not previously known to consume wax. We expected that these wax-competitors could negatively affect wax availability for honeyguides, but instead found that these competitors likely stabilize the mutualism by shifting the benefits toward the early-arriving or guiding birds. A video abstract including clips of wax-eating behaviour is available on Youtube, and further media coverage can be found at New Scientist. We are also thrilled for our co-author, honey-hunter and long-term collaborator from Mbamba village, Orlando Yassene, as this is his first publication.
New study shows that honey-hunter calls vary regionally like dialects
We have published a new study in People and Nature showing that people in northern Mozambique use regionally distinct “dialects” when communicating with honeyguides. Led by Jessica van der Wal, the paper shows that human–honeyguide communication varies across landscapes in ways that mirror regional variation in human languages. Despite these differences in calls, cooperation between people and honeyguides remains successful and important for human livelihoods across the Niassa Special Reserve, suggesting that both species adjust to one another across their shared landscape.
