Nest predation is the most important source of reproductive failure for many bird species, thus placing nests in ‘safe’ locations that minimise predation risk is paramount to maximising fitness. After a nest predation event, some species have be[...]

The Crow Honeyeater (Gymnomyza aubryana) is a critically endangered bird, endemic to the main island of New Caledonia, but it is poorly known owing to its elusive nature. We conducted playback surveys to assess the distribution, habitat preferen[...]

The Pied Imperial-Pigeon (Ducula bicolor) is a summer migrant to northern Australia, and nests colonially on many islands of the Great Barrier Reef, Queensland. Numbers are perceived to have declined as a result of large-scale shooting in the pa[...]

Monitoring of breeding success is important for the effective management of beach-nesting shorebirds, which are vulnerable to impacts of human recreational disturbance and predation by introduced or superabundant native predators. We examined th[...]

Habitat-dependent selection pressures may result in convergence of the characteristics of vocalisation of species living in the same habitat, favouring optimal transmission features. However, competitive interactions for acoustic space between d[...]
