Brood parasitism is the introduction of unrelated progeny into the nest or colony of a host
that then raises the foreign young. This reproductive strategy has evolved independently …

A fundamental question in biology is how diversity evolves and why some clades are more
diverse than others. Phenotypic diversity has often been shown to result from morphological …

Female ornaments have long been considered non-functional, but a paradigm shift has
occurred over the 2 last decades. The adaptive nature of female ornaments is now widely …

Avian obligate brood parasites lay their eggs in the nests of other species that may provide
care for the foreign offspring. Brood parasitism often imparts substantial fitness losses upon …

Social monogamy predominates in avian mating systems, but this strategy seems unlikely
among brood parasites, where the emancipation from parental care should lead to an …

Nest‐sharer avian brood parasites do not evict or otherwise kill host chicks, but instead inflict
a range of negative effects on their nestmates that are mediated by interactions between the …

Decades of research have shown that the coevolutionary arms race between avian brood
parasites and their hosts can promote phenotypic diversification in hosts and brood …

The antagonistic arms races between obligate brood parasites and their hosts provide
critical insights into coevolutionary processes and constraints on the evolution of life history …

Acoustic signalling is vital to courtship in many animals, yet the role of female vocalizations
is understudied. Here, we combine observational and experimental methods to assess the …

Understanding the relationships between cognitive abilities and fitness is integral to an
evolutionary study of brain and behavior. However, these relationships are often difficult to …
