Research on a remarkable
human-animal relationship

Biography

I have spent my life looking towards nature and being in awe of its wonder. I grew up living in a small town in Namaqualand where collecting shells on the bank of the orange river and going camping allowed me to cultivate my love for nature. At a young age I became slightly obsessed with the protection of the environment by becoming a vegetarian and advocating for the introduction of recycling facilities at my high school. To further my reach in the environmental sphere I decided to study environmental and geographical science at UCT as well as biology which would give me further insight into functioning of the system I was determined to protect. I have a particular interest in conservation biology and the interaction with humans and the natural environment. I finished my undergrad with these majors and continued into my honours in Biology. However I persisted in the field of sustainability practices and environmental activism by becoming the head of the Green Campus Initiative which aims to make the institution more environmentally friendly.  

 

Research focus

Throughout my academic career there have been a myriad of subjects that have interested me and occupied most of my time. For the last two years, I have been focussed on birds and more specifically the African Honeyguide. I had attended a research trip in the beginning of third year where I had met this bird for the first time led by Claire Spottiswoode and my other two current supervisors Celiwe Ngcamphalala and Jessica van der Wal and it drove me to read up, increase my bird ringing skills and engage in my very own honeyguide research project. I am currently doing my honours on the question of which other birds outside of honeyguides can consume beeswax. It has been thought that honeyguides are unique among terrestrial birds in being able to consume and digest beeswax, but recent field observations call this into questions. I am analysing several years of camera trap data to ask which species besides honeyguides eat beeswax, and conducting a phylogenetically controlled analysis to test what ecological traits predict wax-eating.

    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.

    New paper on honey-hunting with honeyguides in western Africa

    We are pleased to share our new paper on honey-hunting with honeyguides, in western Africa this time. Led by Wiro-Bless Kamboe as part of his MSc project, and co-authored with Claire Spottiswoode and Timothy Khan Aikins, with Jessica van der Wal as senior author, the study documents honey-hunting practices in northern Ghana and explores the involvement of greater honeyguides. We found that while mutualism persists, it occurs at lower levels than those documented in eastern and southern Africa. Honey-hunters in Ghana often visit known bees’ nests without honeyguides’ help, and discarded beeswax continues to supplement the birds’ diet. We found no clear evidence that socio-economic changes, such as increased access to motorised transport, have disrupted this relationship.
