Activities and research interests:

Claire is an evolutionary biologist and passionate naturalist with a particular interest in the ecology, evolution and conservation of species interactions. She runs two long-term field projects on African birds: one in southern Zambia focusing on coevolution between brood-parasitic birds and the hosts that they exploit to raise their young (see AfricanCuckoos.com), and one in northern Mozambique on the mutually beneficial interactions between honeyguides and the human honey-hunters with whom they cooperate to gain access to bees’ nests (see at AfricanHoneyguides.com). Both projects involve close cooperation with rural communities, and rely on their local field knowledge and skill.

Claire works jointly at the FitzPatrick Institute (as Pola Pasvolsky Chair in Conservation Biology) and at the University of Cambridge in the UK (as Principal Research Associate and Hans Gadow Lecturer). Claire is from Cape Town and did her undergraduate studies at the University of Cape Town (1998–2001), followed by PhD research (2002–2005) at the University of Cambridge under the supervision of Professor Nick Davies. She continued at Cambridge with the kind support of various research fellowships, and in mid-2016 returned to South Africa to start a joint position at the FitzPatrick Institute. She supervises research students and teaches at both universities.

Most of Claire’s work is inspired by field observations and, with the help of students, postdocs and interdisciplinary collaborators, she tries to integrate field experiments with approaches drawn from other fields. She has greatly enjoyed collaborating with experts in evolutionary genetics, sensory biology, anthropology, biophysics, applied mathematics, and other fields.

Claire and her team work on both parasitic and mutualistic interactions between species. Since 2006, she has been working on coevolutionary arms races between brood-parasitic birds (such as cuckoos, honeyguides and parasitic finches) and the host species they exploit to bear the costs of raising their young. Together with collaborators, she has focussed on two main questions: first, asking how coevolution can escalate into ongoing arms races involving defensive egg signatures in hosts, and mimetic forgeries in parasites. Second, incorporating genetic approaches, asking how host-specificity can evolve within parasitic species that exploit multiple hosts. This research happens at a field site in southern Zambia, enabled by a wonderful team of local field assistants, and supported primarily by the BBSRC, Leverhulme Trust, Royal Society, and DST-NRF Centre of Excellence at the FitzPatrick Institute. Please see AfricanCuckoos.com for more information about this and other ongoing field projects in Zambia.

Claire is also fascinated by the evolution, ecology and conservation of mutually beneficial interactions between species. Since 2013, she and her team have studied the remarkable mutualism between human honey-hunters and greater honeyguides (Indicator indicator) that lead them to wild bees’ nests. They work primarily in Mozambique’s beautiful Niassa Special Reserve, in collaboration with the honey-hunting community of Mbamba Village and the Niassa Carnivore Project, and supported by a Consolidator Grant from the European Research Council. Please see AfricanHoneyguides.com for more information about this project.

Back in South Africa, Claire is working with former postdoc Dr Anina Coetzee (now a Lecturer at Nelson Mandela Metropolitan University) on how sunbird pollinators may be driving the astonishingly diverse radiation of bird-pollinated Erica species in the Cape Floristic Region’s fynbos vegetation.

Claire has wide interests in ornithology and has also worked on avian sociality, nest camouflage, sexual selection, and bird migration, as well as the conservation ecology of threatened species particularly in the Horn of Africa and northern Mozambique. She is a life-long birdwatcher and has co-authored three birding guidebooks to Ethiopia and southern Africa. She currently serves on the Executive Council of the International Society for Behavioural Ecology, and is a Senior Research Fellow at Magdalene College in Cambridge.
