Comparative analyses used to reconstruct the evolution of traits associated with the human
language faculty, including its socio‐cognitive underpinnings, highlight the importance of …

A growing number of studies ask whether and how bird songs vary between areas with low
versus high levels of anthropogenic noise. Across numerous species, birds are seen to sing …

Research on bird song has contributed to important advances in diverse biological fields
from neurobiology to conservation biology. Bird song has traditionally been studied as an …

In birds, anthropogenic noise has been linked to reduced breeding densities and success,
but the mechanisms by which this occurs are currently unclear. In this study, we investigated …

The evolution of sexually monomorphic (ie mutual) ornamentation has attracted growing
attention as a 'blind‐spot'in evolutionary biology. The popular consensus is that female …

Body size is a key sexually selected trait in many animal species. If size imposes a physical
limit on the production of loud low-frequency sounds, then low-pitched vocalisations could …

Social interactions are central in the lives of many animals. Social partners can lower
individual stress levels (Rault, 2012), a process known in humans and primates as social …

Seasonal timing is studied by ecologists and physiologists alike and it is now widely
recognized that further integration of these fields is needed for a full understanding of …

Highlights•Females might use song to communicate with males or to compete with other
females.•We measured female and male song across stage, and in response to female …

Spectral and temporal measures of vocalizations have been found to correlate with physical
parameters that affect the fighting ability in various species of frogs, mammals, and birds …
