In my research I use avian model systems to investigate key issues in behavioural and sensory ecology: how animals communicate with each other, and why communication signals have evolved into certain designs. Being especially curious about signals and cues involving sound, I have conducted research into vocal mimicry, the dawn chorus, and song dialects (among others). My current research focus is on the functional significance of complex signals – signals made up of multiple components expressed in one or more sensory modalities. Specifically, I am investigating the function and evolution of integrated song and ‘dance’ displays. I have the great privilege of examining this topic using the superb lyrebird, Menura novaehollandiae, as a model species.
