We have broad interests in behavioural ecology, particularly acoustic communication and breeding biology in birds. Our current work is focussed on communication about danger, eavesdropping among species, and vocal mimicry. See the 'Wildlife Australia' article below, for a non-technical introduction to our work on alarm calls and eavesdropping in avian communities.
In addition to our current projects, we have worked on duetting, brood division, hatching asynchrony, egg size, life-history and cooperative breeding in birds.
