Actions taken to control the coronavirus disease 2019 (COVID-19) pandemic have
conspicuously reduced motor vehicle traffic, potentially alleviating auditory pressures on …

Anthropogenic noise imposes novel selection pressures, especially on species that
communicate acoustically. Many animals—including insects, frogs, whales and birds …

Animals modify acoustic communication signals in response to noise pollution, but
consequences of these modifications are unknown. Vocalizations that transmit best in noise …

Interactive communication occurs when two or more individuals reciprocally exchange
signals. It is widespread and common in humans, non-human animals, and even machines …

As urbanization expands globally, the communication systems of an increasing number of
species are affected. Because bird song is a long-distance signal used to attract mates and …

Song production across many songbird species is shaped by largely conserved sets of
constraints associated with song control, production, and perception. This chapter …

Urban environments have some of the most highly modified soundscapes on the planet,
affecting the way many animals communicate using acoustic signals. Communication …

In birds, song performance determines the outcome of contests over crucial resources. We
hypothesized that 1) sustained performance is limited within song, resulting in a …

Many songbirds sing intensely during the early morning, resulting in a phenomenon known
as the dawn chorus. We tested the hypothesis that male Adelaide's warblers (Setophaga …

Sexual signals that are physically limited can be reliable indicators of quality or motivation in
male–male competition. One such example of a motor constraint in birds is the production of …
