Potential cooperation between honey badgers and honeyguides may have implications for the origins of our own species’ cooperation with honeyguides and for the ecology and conservation of both honey badgers and honeyguides.

Ricardo Guta, our dear colleague and friend in our research team, tragically died on 1 December 2022 following a swimming accident in the Cape mountains. All our thoughts are with his wife, Lailat, and their children Adrielle and Piotr. Ricardo’s life was honoured by his colleagues in a memorial at the University of Cape Town on 9 December 2022. He will soon be laid to rest by his family in his home city of Beira, Mozambique.

Ricardo’s warm and generous personality and passion for natural history touched everyone he met. He was much loved and respected at Gorongosa National Park where he worked as an entomologist, at the University of Cape Town where he had just completed his MSc studies, and at the Niassa Special Reserve where we recently carried out a wonderful field trip together. Ricardo had just begun his PhD in our research team, studying the influence of honeyguide-human mutualism on honeybee ecology. We are heartbroken to have lost a wonderful scientist, conservationist and human being, and we miss him deeply.

Ricardo’s legacy will live on in our team as we remember his joy and optimism, and his remarkable capacity to bring people together.

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...
