Superb Fairy-wrens (Malurus cyaneus). Since 2005, we have been monitoring superb fairy-wrens in South Australia. New to science, we discovered that mothers vocally tutor their embryos. Incubating females adaptively adjust their incubation calling behaviour, which enhances offspring vocal learning and survival against the brood parasite Horsfield’s Bronze Cuckoo (Chrysococcyx basalis). This long term project explores how birds communicate and interact socially, and how behaviours influence their survival in changing environments.

Little penguins (Eudyptula minor). Since 2012, we have been monitoring little penguins in South Australia to uncover the drivers behind their population decline. Living under constant pressure from human disturbance and other stressors, these seabirds face challenges that can erode fitness, survival, and breeding success. Using long-term data, this project investigates how penguins cope with chronic stress and identifies the biological and environmental factors that shape their ability to persist in an increasingly altered world.

Seabirds and shorebirds. This multi-species project explores the behavioural ecology of seabirds and shorebirds in South Australia to inform effective, targeted conservation strategies. Focusing on the influence of human presence and coastal activities, the research examines how environmental pressures shape behaviours and diet, with the aim of improving management and long-term conservation outcomes.
