How do parents recognize their offspring when the cost of making a recognition error is high
[1–3]? Avian brood parasite-host systems have been used to address this question because …

Fairy-wrens (genus Malurus) maintain territories year round, and breed cooperatively, with
all members of the social group provisioning young. Despite living with several adult males …

Abstract Extra‐pair paternity (EPP), where offspring are sired by a male other than the social
male, varies enormously both within and among species. Trying to explain this variation has …

Fairy-wrens (Malurus) are socially monogamous and yet exhibit among the highest rates of
extra-pair paternity (EPP) known in passerine birds. Here, we review patterns of EPP in fairy …

Prenatal imitative learning is an emerging research area in both human and non-human
animals. Previous studies in Superb Fairywrens (Malurus cyaneus) showed that mothers are …

Island organisms often evolve phenotypes divergent from their mainland counterparts,
providing a useful system for studying adaptation under differential selection. In the white …

Personality syndromes in animals may have adaptive benefits for survival. For example,
while engaging in predator deterrence, reactive individuals tend to prioritise their own …

Birdsong is regarded as a classic example of a sexually-selected trait and has been
primarily studied in systems with male song. Complex solo female song is emerging from the …

Historically, bird song complexity was thought to evolve primarily through sexual selection
on males; yet, in many species, both sexes sing and selection pressure on both sexes may …

Variation in the acoustic structure of alarm signals has mainly been viewed as coding
information about the type of predator or the level of threat posed by the predator. Alarm …
