Susie grew up in New Zealand and obtained her BSc in Ecology & Biodiversity from Victoria University of Wellington. She completed her honours and PhD at Massey University in the Manawatu, working initially on the foraging behaviour of kiwi, and expanding her research into non-visual senses used by probing birds, including kiwi (Apterygidae), ibises (Threskiornithidae) and shorebirds (Scolopacidae). Susie discovered that a unique anatomy and associated vibro-tactile sense thought only to exist in shorebirds has also evolved in kiwi and ibises – suggesting a beautiful case of convergent or parallel evolution. Susie’s PhD was awarded in 2011.

Susie accepted a post doctoral fellowship at the Fitztitute in 2010 to work on the ‘Hot Birds’ desert birds and climate change programme, in conjunction with Prof. Phil Hockey and core Centre of Excellence team member Prof. Andrew McKechnie (University of Pretoria). Following Phil’s sad and untimely passing in 2013, Susie accepted an extension to her fellowship to continue managing the University of Cape Town branch of ‘Hot Birds’ in collaboration with Prof. McKechnie. Susie was appointed to the post of Lecturer in 2015 and is continuing the ‘Hot Birds’ programme as well as taking a hand in the co-ordination of the Conservation Biology Masters course.

Research interests

Hot birds: understanding the vulnerability of arid zone birds to climate change: A major focus of Susie’s current research is the use of mechanistic approaches to understand the potential vulnerability of different bird species to climate change. Together with her collaborators and students, she studies the behavioural and ecophysiological responses of birds to high temperatures, with a focus on fitness consequences associated with thermoregulatory trade-offs. Susie works closely with Prof. Andrew McKechnie and Dr Ben Smit on these questions, using predominantly Kalahari species, but also fynbos birds, as model taxa.

Behavioural ecology in a changing world: Susie is interested in the behavioural flexibility of animals in the face of ecological change: how environmental factors, particularly temperature and aridity, drive behavioural decisions. She is especially interested in the consequences of these decisions for individual fitness, sociality, and the evolution of life history strategies.

Sensory ecology: Susie is particularly interested in the non-visual senses used by animals –especially birds - in foraging and social interactions, the ecological pressures that lead to the favouring of non-visual senses, and the connections between sensory systems and behaviour.
