Interspecific information flow is known to affect individual fitness, population dynamics and
community assembly, but there has been less study of how species diversity affects …

In several animal species, an alarm call (eg ABC notes in the Japanese tit Parus minor) can
be immediately followed by a recruitment call (eg D notes) to yield a complex call that …

Mobbing is an important anti-predator behavior where prey harass and attack a predator to
lower the immediate and long-term risk posed by it, warn others, and communicate about the …

Interceptive eavesdrop** on the alarm calls of heterospecifics provides crucial information
about predators. Previous research suggests predator discrimination, call relevance …

Within species, vocal and auditory systems presumably coevolved to converge on a critical
temporal acoustic structure that can be best produced and perceived. While dogs cannot …

Referential alarm calls that denote specific types of dangers are common across diverse
vertebrate lineages. Different alarm calls can indicate a variety of threats, which often require …

Animals vary in the sophistication of their capacities for social learning, and much research
has focused on establishing when learning from others is favourable. However, social …

Highlights•Participants in mixed-species bird flocks were similar in body mass.•Flocks were
dominated by smaller species that were highly vocal.•Flock participants were not similar in …

Highlights•Noise might stop animals responding to calls via masking, distraction or
vigilance.•We tested mechanisms using playback of heterospecific bird alarm calls and …
