Avian migration clocks in a changing world

Journal of Comparative Physiology A, Journal Year: 2024, Volume and Issue: 210(4), P. 691 - 716

Abstract Avian long-distance migration requires refined programming to orchestrate the birds’ movements on annual temporal and continental spatial scales. Programming is particularly important as typically anticipate future environmental conditions. Hence, has long been of particular interest in chronobiology. Captivity studies using a proxy, shift nocturnality during seasons (i.e., migratory restlessness), have revealed circannual circadian regulation, well an innate sense direction. Thanks rapid development tracking technology, detailed information from free-flying birds, including annual-cycle data actograms, now allows relating this mechanistic background behaviour wild. Likewise, genomic approaches begin unravel many physiological pathways that contribute migration. Despite these advances, it still unclear how programmes are integrated with specific conditions experienced journey. Such knowledge imminently environments undergo anthropogenic modification.

Abstract Background Many species are exhibiting range shifts associated with anthropogenic change. For migratory species, colonisation of new areas can require novel programmes that facilitate navigation between independently-shifting seasonal ranges. Therefore, in some cases range-shifts may be limited by the capacity for to transferred generations, which genetically and socially mediated.

Social learning and culture in birds: emerging patterns and relevance to conservation

Philosophical Transactions of the Royal Society B Biological Sciences, Journal Year: 2025, Volume and Issue: 380(1925)

There is now abundant evidence for a role of social learning and culture in shaping behaviour range avian species across multiple contexts, from migration routes geese foraging crows, to passerine song. Recent emerging has further linked fitness outcomes some birds, highlighting its potential importance conservation. Here, we first summarize the state knowledge on focusing best-studied contexts migration, foraging, predation We identify extensive gaps taxa but argue that existing suggests that: (i) are taxonomically clustered (ii) reliance one behavioural domain does not predict others. Together, use this build predictive framework aid conservationists species-specific decision-making under imperfect knowledge. Second, review link between conservation birds. understanding which behaviours birds likely learn socially can help refine strategies, improving trajectories threatened populations.

Making better use of tracking data can reveal the spatiotemporal and intraspecific variability of species distributions

Understanding geographic ranges and species distributions is crucial for effective conservation, especially in the light of climate land use change. However, spatial, temporal intraspecific resolution digital accessible information on often limited. Here, we suggest to make better high‐resolution tracking data address existing limitations occurrence records such as spatial biases (e.g. lack observations parts range), during a certain period year), insufficient variability population‐ or individual‐level variation). Addressing these gaps can improve our knowledge ranges, intra‐annual changes distributions, population‐level differences habitat space use.
