Summary: In this study, a deep learning-based image segmentation pipeline is developed to extract information on plumage UV reflectance from bird photographs. The results demonstrate that UV reflectance is widespread and phylogenetically conserved in passerine birds, and the light environment plays a significant role in promoting the evolution of UV plumage colouration.

Summary: Both residential areas and urban forest fragments can provide stopover habitat for migrating birds. The study aimed to determine which species prefer urban forest fragments or adjacent residential areas during migration and whether different vertical strata guilds of birds are associated with different habitats. The results showed that under-canopy birds significantly preferred urban forest fragments, while canopy birds used both habitats more equally. Residential neighborhoods with vertical vegetation structure had more bird species. This highlights the importance of conserving and restoring certain vegetative characteristics in urban ecosystems.

Summary: The study found that the richness of passerine species is influenced by multiple factors in the Korean peninsula, which counter the global latitudinal gradient. The complex mechanism of the peninsular effect in the peninsula involves climate, habitat area, and migrant species inflow.

Summary: Nest location is crucial for bird reproduction. This study used a comparative framework to analyze the evolutionary history, biogeographical and habitat variation, and associations with life history traits of ground nesting behavior in passerine birds. The results showed scattered phylogenetic distribution of ground nesting and strong evolutionary lability between ground and non-ground nesting. Ground nesting was associated with open habitats and higher latitudes, as well as fast life histories. This study provides a foundation for understanding the macroevolution of ground nesting behavior in passerine birds.

Summary: This paper examines the relationship between migration patterns and migrant workers' consumption, showing significant differences in consumption among different migration patterns. The consumption structure of migrant workers is in line with migration theory and life cycle theory, providing insights for policymakers to design effective policies for improving migrant workers' consumption levels.

Summary: There are differences in migration patterns and habitat-use among different subpopulations of wintering Eastern Tundra Bean Geese. Although migration distances are similar, there are differences in migration duration and stopover duration in spring. Habitat-use differs significantly in winter, suggesting adaptations and responses to different environmental conditions encountered along migration routes.

Summary: Studies on the migration patterns, habitat use, and conservation of the Eastern common crane Grus grus lilfordi in East Asia are insufficient. This study explores the migration pattern, habitat use, and conservation status of the Eastern common crane. The cranes migrated an average of 1581.5 km in autumn and 1446.5 km in spring between their breeding site in Eastern Mongolia and the following wintering sites.

Summary: This study investigated the spawning grounds and habitat use patterns of Acanthopagrus latus in the waters surrounding the Wanshan Islands in China. The findings revealed that the spawning area of A. latus originated from low to medium-salinity waters with mangroves and oyster farm habitats in the Pearl River Estuary. A. latus showed widespread migration between estuarine and marine habitats throughout its life cycle. These results have important implications for future fisheries management.

Summary: This study investigated the movements and behaviors of whale shark individuals tagged in Panama. The results showed that whale sharks mainly foraged within Panama's exclusive economic zone but also migrated along the coast and out to the open ocean. Foraging behavior was associated with higher productivity and chlorophyll concentration, while higher eddy speeds were observed during migration. The study also highlighted the overlap between the whale shark's habitat and areas of industrial fishing and marine vessel traffic.

Summary: The Hailuo Valley in Mt. Gongga, Southwest China, is an ideal location for studying the altitudinal migration behavior of birds. Temperature and humidity are correlated with bird abundance, where increasing temperature leads to upward migration and increasing humidity leads to downward migration. Invertebrate biomass may be an important ecological driver for the altitudinal migration of birds feeding on insects.

Summary: Billions of birds migrate from the Palaearctic to sub-Saharan Africa, with Eurasian Golden Orioles historically utilizing two major wintering grounds over the past 200 years. The relative use of these areas between 1895 and 1971 depended on local rainfall intensities. The species may strongly depend on humid wintering areas in sub-Saharan Africa, potentially putting them at risk as the global climate continues to change.

Summary: Migration plays a significant role in the transmission of parasites, with migratory birds potentially introducing new parasite strains to new areas and hosts. The presence of migrants may negatively impact local parasite richness, but is not associated with local prevalence, demonstrating their potential role in enhancing pathogen spread and influencing parasite community transmission.

Summary: Near-term ecological forecasting can help mitigate negative impacts on wildlife by providing timely and relevant predictions, as demonstrated in a study focusing on avian migration in the United States. Dynamic mitigation strategies based on dynamic forecasts were found to require fewer action nights compared to static conservation strategies based on fixed time windows.

Summary: The number of temperate-breeding Canada geese in the Atlantic and Mississippi Flyway has increased significantly since the 1980s, leading to an increase in the number of pre-molt migrants. This provides hunting opportunities for Cree hunters living near James Bay. A study on the movement patterns and habitat use of molt migrant Canada geese along the east coast of James Bay revealed that they prefer tidal flats and salt marshes in spring, and inland freshwater wetlands, peatlands, and tidal flats in autumn. Molt migrant geese can increase hunting opportunities and provide supplementary wildlife food for Cree communities.

Summary: Spring in Europe has been trending earlier for almost half a century, leading to earlier arrival of long-distance migrant birds. Climate change has been considered as a factor contributing to this phenomenon, but additional cues triggering migration weeks earlier and thousands of kilometres away must exist. This study found that climate variables in Africa and Europe can explain the variability in timing of arrival for long-distance migrant passerines in spring.
