研究领域
Research in the Mennill Sound Analysis Lab focuses on the ecology and evolution of communication and mating systems of wild animals. My students and I study the interaction between animal communication and reproductive strategies, and the influence of natural selection and sexual selection on vocal behaviour and mating behaviour. We focus heavily on the behavioural ecology of birds but we also study frogs and mammals. I am a field biologist; my students and I combine our laboratory-based research with an intensive field-based approach to study the behavioural ecology of animals in their natural environment. Together with a variety of collaborators, I maintain ongoing studies of chickadees and sparrows in Canada, and wrens, manakins, and toads in Costa Rica.
