Abstract Background Migratory birds possess remarkable navigational adaptations. Vagrants, few individuals who migrate to incorrect locations, offer a unique opportunity study how navigation is accomplished. Vagrancy may occur due external factors forcing off course, such as strong wings, or errors. Natural disruptions in the Earth’s magnetic field cause errors interfering with bird magnetoreception. Failures of other tools like visual landmark recognition and social route learning also contribute vagrancy, but these are difficult quantify. Methods I used eBird, community science dataset comprising millions observations, relative likelihood offshore vagrancy under different including weather, geomagnetic disturbance, solar activity using mixed effects logistic regression. Then, studied variation species propensity be driven by morphology migration distance multiple linear regression, inheritances alleles phylogenetic analysis.

Haemoproteus blood parasites of birds are thought to be relatively benign. Recent findings show that infections may develop in the brain birds, possibly distorting their orientation sense. Misdirected migration lead migrants outside range where they recognized as vagrants and can transmit novel hosts.

Understanding the factors that determine occurrence and strength of ecological interactions under specific abiotic biotic conditions is fundamental since many aspects community stability ecosystem functioning depend on patterns among species. Current approaches to mapping food webs are mostly based traits, expert knowledge, experiments, and/or statistical inference. However, they do not offer clear mechanisms explaining how trophic affected by interplay between organism characteristics physical environment, such as temperature, light intensity or viscosity. Hence, cannot yet predict accurately local will respond anthropogenic pressures, notably climate change species invasions. Herein, we propose a framework synthesises recent developments in food-web theory, integrating body size metabolism with properties ecosystems. We advocate for combination movement paradigm modular definition predation sequence, because central predator-prey interactions, generic, model needed describe all possible variation interactions. Pending sufficient empirical theoretical our help impacts well-studied factors, temperature oxygen availability, well less commonly considered variables wind, turbidity electrical conductivity.

Understanding why certain species occupy wider climate niches than others is a fundamental pursuit in ecology with important implications for conservation and management. However, existing synthesis on this topic has focused the consequences rather causes of niche expansion, leading to significant gaps our understanding possible evolutionary drivers ecological property. Here we leverage distribution models powered by millions citizen science sightings birds determine how comprehensive suite parameters influences breadth niches. Our analyses show that migration more central locations space are directly associated Additionally, they indicate larger brains, smaller bodies, broader dietary requirements indirectly narrower niches, presumably because enable occupancy geographically widespread habitats narrow areas space.

Overall, findings shed light critical, yet highly underappreciated properties underscoring complexity interconnectivity shaped their evolution among birds.

Understanding the occurrence of vagrant individuals away from their usual distribution range can shed light on animal navigation systems. In autumn, migratory Nearctic landbirds often occur as far Western Europe, and while link between these occurrences wind conditions over Atlantic Ocean is largely established, drivers natal origins transatlantic vagrants remain elusive. We conducted feather hydrogen isotopic (δ2Hf) analyses 72 representing 26 landbird species captured in Azores (Portugal), Iceland France last century to infer likely origins. While potential several came northeastern populations (e.g., Blackpoll Warbler, Northern Parula), we also found that some originated northwestern American Redstart, Gray-cheeked Thrush) or southern (Yellow-billed Cuckoo) populations. Our results confirm migrating along coast undertaking over-water flights are more be displaced. However, they show even southeast towards eastern North America have displaced across Ocean. Further research needed fully understand vagrancy events determine whether only factor push off intended course. Overall, this study sheds broad geographic transoceanic implications for colonization new regions.

Despite known dependence of birds and other animals on cues for successful seasonal migrations, potential effects space weather organisms that use Earth’s magnetic field navigation have received little study. We tested whether disturbances are associated with disruptions to bird migration at a macroecological scale. leveraged long-term radar data characterize nightly dynamics nocturnally migrating North American avifauna over 22 y. then used concurrent magnetometer develop local disturbance index each station (ΔBmax), facilitating spatiotemporally explicit analyses relationship between disturbance.
