The interactions between avian obligate interspecific brood parasites and their hosts provide
tractable systems for studying coevolutionary processes in nature. This review highlights …

Research on avian vocalisations has traditionally focused on male song produced by oscine
passerines. However, accumulating evidence indicates that complex vocalisations can …

Social organisation in animals takes many forms. It includes assemblages of territorial
animals, dominance hierarchies and social groups, among other things. The basic tenet that …

Ecology is a fundamental driving force for the evolutionary transition from solitary living to
breeding cooperatively in groups. However, the fact that both benign and harsh, as well as …

The statistical estimation of phylogenies is always associated with uncertainty, and
accommodating this uncertainty is an important component of modern phylogenetic …

Aim How population density varies across animal species in the context of environmental
gradients, and associated migratory strategies, remains poorly understood. The recent influx …

Environmental noise from anthropogenic and other sources affects many aspects of animal
ecology and behaviour, including acoustic communication. Acoustic masking is often …

The relationships between avian brood parasites and their hosts are widely recognised as
model systems for studying coevolution. However, while most brood parasites are known to …

Ecological constraints on independent breeding are recognised as major drivers of
cooperative breeding across diverse lineages. How the prevalence and degree of …

In her comprehensive and carefully crafted book, Gisela Kaplan demonstrates how
intelligent and emotional Australian birds can be. She describes complex behaviours such …
