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
