Tactics of evasion: strategies used by signallers to deter eavesdropping enemies from exploiting communication systems
Eavesdropping predators, parasites and parasitoids exploit signals emitted by their prey and
hosts for detection, assessment, localization and attack, and in the process impose strong …

When does early‐life telomere length predict survival? A case study and meta‐analysis
Suboptimal conditions during development can shorten telomeres, the protective DNA caps
on the end of chromosomes. Shorter early‐life telomere length (TL) can indicate reduced …

Cooperative breeding and the emergence of multilevel societies in birds
Multilevel societies (MLSs), where social levels are hierarchically nested within each other,
are considered one of the most complex forms of animal societies. Although thought to …

Birds learn socially to recognize heterospecific alarm calls by acoustic association
Animals in natural communities gain information from members of other species facing
similar ecological challenges [1–5], including many vertebrates that recognize the alarm …

Reconciling ecogeographical rules: rainfall and temperature predict global colour variation in the largest bird radiation
Ecogeographical rules that associate climate with organismal form and function can reveal
patterns of climatic adaptation. Two rules link animal coloration with climate: Gloger's rule …

Evolutionary drivers of seasonal plumage colours: colour change by moult correlates with sexual selection, predation risk and seasonality across passerines
Some birds undergo seasonal colour change by moulting twice each year, typically
alternating between a cryptic, non‐breeding plumage and a conspicuous, breeding …

Conspicuous plumage does not increase predation risk: a continent-wide test using model songbirds
The forces shaping female plumage color have long been debated but remain unresolved.
Females may benefit from conspicuous colors but are also expected to suffer costs …

[HTML][HTML] Multilevel social structure predicts individual helping responses in a songbird
Multilevel societies are formed when stable groups of individuals spatially overlap and
associate preferentially with other groups, producing a hierarchical social structure. 1 Once …

On how risk and group size interact to influence vigilance
G Beauchamp - Biological Reviews, 2019 - Wiley Online Library
Vigilance allows animals to monitor their surroundings for signs of danger associated with
predators or rivals. As vigilance is costly, models predict that it should increase when the risk …
