Testing the Mediating Role of Social Interactions on the Relationship Between Age and Plumage Traits on Reproductive Success

Ethology, EarlyView.
This conceptual figure uses Directed Acyclic Graphs (DAG) to represent the hypothesized biological mechanism in which age and/or plumage traits affect reproductive success, and social interactions mediate these relationships. It highlights the predicted decomposition of (a) the total effect into the direct and indirect effects under scenarios of (b ...

Contributions of Positive Social Interactions to Vocal Learning and Social Cohesion

Ethology, EarlyView.
Birdsong produced in non‐breeding flocks is shaped by a dynamic interplay between intrinsic reward and social feedback. Studies in cowbirds and starlings suggest that positive affective states and opioid‐mediated reward promote song practice, while responses from flock mates, potentially reinforced by dopaminergic mechanisms, refine species‐typical ...

Corpses as Repositories of Information and Funerals as Information Centres: Why Natural Selection Favours the Bereaved

Ethology, EarlyView.
Corpses are repositories of information about the cause of death. The distress of the bereaved acts as an honest signal drawing conspecifics to the body, enabling them to learn quickly about the death, adapt their behaviour, and spread knowledge of threats across multiple social levels.

Continued population recovery and high annual survival rates of White‐rumped Vultures in Nepal

Ibis, EarlyView.
Populations of Gyps vultures in South Asia underwent catastrophic declines caused by unintentional poisoning by the veterinary drug diclofenac. Since the drug was banned in 2006–2010, declines have halted across the region, including in Nepal. The present study updates population trends of G.

Exploration speed in Red Knots affects spring migration timing, but only after experimentally constrained fuelling conditions

Ibis, EarlyView.
Individual variation in avian migration timing is still poorly understood, yet recent evidence shows that it is closely linked to personality traits and may also be affected by food availability. Here, we examined how the interaction of the personality trait exploration speed and food availability affected the departure timing of Red Knots Calidris ...
