Activities and research interests

Claire is interested in the evolution, ecology and conservation of species interactions. She works jointly at the FitzPatrick Institute (as Pola Pasvolsky Chair in Conservation Biology) and at the University of Cambridge in the UK (as a BBSRC David Phillips Research Fellow 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 started a joint position at the FitzPatrick Institute, working part-time at both universities.

Most of her work is inspired by field observations, and she tries to integrate field experiments with other approaches drawn from population genetics, sensory ecology, and comparative analyses across species.

Claire and her team work on both parasitic and mutualistic interactions between species. For over a decade, 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 areas. First, asking how hosts evolve defensive adaptations against brood parasites that mimic their eggs, such as visual 'signatures' of identity that are difficult for parasites to forge. Second, asking what genetic mechanisms can allow a single parasitic species to evolve specialised adaptations (such as egg mimicry) to exploit multiple host species at once.  Much of Claire’s research happens at a field site in southern Zambia where she has worked together with a wonderful team of local assistants since 2006, and where several colleagues from Cambridge and Cape Town now work too. Please see www.africancuckoos.com for more information about this and other ongoing field projects in Zambia.

More recently Claire has also begun working on the evolution, ecology and conservation of mutually beneficial interactions between species. In Mozambique’s beautiful Niassa National Reserve, and in collaboration with the Niassa Carnivore Project, she and her colleagues study the remarkable mutualism between human honey-hunters and greater honeyguides (Indicator indicator) that lead them to wild bees’ nests. Since 2017, this project has been supported by a Consolidator Grant from the European Research Council.

Back in South Africa, postdoctoral fellow Dr Anina Coetzee at the University of Cape Town is leading work 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 editorial board of Biology Letters, and is a Senior Research Fellow at Magdalene College in Cambridge.
