Humans become more selective with whom they spend their time, and as a result, the social networks of older humans are smaller than those younger ones. In non-human animals, processes such competition opportunity can result in patterns declining sociality age. While there is support for age mammals, evidence from wild bird populations lacking. Here, we test whether declines wild, insular population, where know exact ages individuals. Using 6 years data, find that birds aged, degree betweenness decreased. The number same-age still alive also decreased Our results suggest longitudinal change may be, part, an emergent effect natural changes demography. This highlights need to investigate changing costs benefits across lifetime. article part discussion meeting issue ‘Understanding society using populations’.

Ageing affects almost all aspects of life and therefore is an important process across societies, human non-human animal alike. This article introduces new research exploring the complex interplay between individual-level ageing demography, consequences this holds for structure functioning societies various natural populations. We discuss how Special Issue provides a foundation integrating perspectives from evolutionary biology, behavioural ecology demography to provide insights into shapes individuals’ social behaviour associations, in turn impacts networks, processes (such as disease or information transfer) fitness. Through examining these topics taxa, invertebrates birds mammals, we outline contemporary studies are using populations advance our understanding relationship age society innovative ways. highlight key emerging themes Issue, such sociality lifespan health, genetic ecological underpinnings adaptive strategies employed by different species. conclude that underscores importance studying diverse systems interdisciplinary approaches advancing both more generally. part discussion meeting issue ‘Understanding ’.
