My research is mainly focused around the following areas:
- Birdsong: evolution & function
- Social adaptation: the evolution of song dialects
- Urban behavioural adaptations
- Social learning, cooperation & leadership (using guppies)
Bird Song: evolution & function
Much of my research centres around avian communication. Why do birds sing? What response does song elicit in other birds? How & why do songs change over time? I am particularly interested in how signals adapt and change in response to both environmental and sexual selection pressures.
Urban behavioural adaptations
I am investigating how and why animals adapt their behavioural strategies in response to this background noise. For example, some birds sing at a higher pitch in noisy cities than they do in quieter rural areas. I am researching how these behavioural differences emerge, the role that learning plays in reinforcing these differences, and the implications these changes have for conservation and biodiversity.
This research includes the Nestbox Survey, involving regular monitoring of nearly 200 nest boxes in the University woodlands by a team of student volunteers.
Social adaptation: the evolution of song dialects
Animals may adapt their behaviours for a variety of reasons, including the need to “fit in” with their neighbours. For example, songs of corn buntings form a pattern of local dialects. I am investigating the role of social adaptation and dialects in signalling systems and the implications for these systems of changes to farming practice and population decline.
Social learning: information transfer within groups
Animals often learn new behaviours from other individuals, so knowing who to trust and when to go it alone are important decisions. Using the University’s aquarium facilities, I am studying social learning in guppies to investigate how animals decide who to learn from as well as how they actually learn and how much they can learn from one another. This work also investigates leadership, personality, rational choice and cooperation among individuals and groups.
