Biography

Research interests
My research field is the ‘Evolution of Cognitive Abilities in Birds’ with a strong interest in the interaction between behaviour and ecology, particularly cognitive ecology. I investigate how evolutionary forces such as ecological factors, social organization, and life-style have shaped information gathering, learning, and memory on the species, population and individual (personality traits) level. My research involves basic as well as applied research (animal welfare, conservation). I use cost/benefit considerations to predict cognitive differences on the species to the individual level and integrate behavioural and physiological methods.

Study animals:
I have worked with a variety of parrot species (>80 species) and, more recently, with old-world (warblers, tits, chats) and new-world songbirds (icterids). Currently, the Gouldian finch is my study subject.

Research projects
• Personality traits in relation to colour polymorphism in the Gouldian finch
• Neophobia in Gouldian finches
• Background preferences in Gouldian finches
• Assessing habitat requirements of the strongly declining Rusty blackbird
• Feather conditions in young corvids

Current PGR students:
• Georgina R. Eccles: Habituation processes in neophobia reactions
• Alexandra R. Hawthorn: Investigation into the causes of bad feather condition in young corvids admitted to Rehabilitation Centres

Former PGR students:
• Yvette L. Foulds (MPhil): The effectiveness of mixed species aviaries in terms of bird breeding and survival within zoological collections.
• Leah J. Williams (PhD): Leadership and personality traits in the Gouldian finch (Erythrura gouldiae); in collaboration with Dr. Andrew J. King, Department of Bioscience, College of Science, Swansea University, Swansea, UK (funded by the School of Natural Sciences & Psychology with HEFCE research allocation)
