Summary: Twice-a-year, large-scale migration of billions of birds is a fascinating phenomenon driven by the interaction of endogenous rhythm with photoperiod and temperature. The success of these migratory journeys depends on their synchronization with other annual sub-cycles and is marked by changes in behavior, physiology, and gene expression. In this study, the genetic basis of migratory behavior is explored using passerine migrants, specifically the blackheaded and redheaded buntings.

Summary: Based on the study of Cyprus wheatears, we found that age has an impact on migratory behavior, with early adaptation occurring during the first annual cycle. Juveniles depart and arrive later than adults, but there are no significant differences in the duration of migration and route directness. Additionally, the timing of migration and non-breeding locations are repeatable for adults but not for juveniles.

Summary: By comparing the temporalities of work and social life among male Bangladeshi-origin migrants in northeast Italy and London, this study reveals stark contrasts in migrants' daily lives in the two settings and the impacts of moving between them. While capitalism shaped class dynamics in both settings, there were marked differences in the routinization of migrants' work and social and family life.

Summary: Residential segregation, especially of rural migrants, is a growing concern in China. This study examines the factors contributing to this spatial separation in Shijiazhuang, a second-tier Chinese city, using advanced multilevel modeling techniques. The findings reveal that migrant status is a more important determinant of segregation than occupation, highlighting the need to analyze intersectional segregation and its constituent parts.

Summary: The number of subsea cables in the marine environment is expected to increase significantly, potentially disrupting the magnetic orientation and navigation of marine animals that rely on magnetic cues. Studies on the impact of anthropogenic magnetic fields on marine species should be prioritized due to their cultural, economic, and conservation value.

Summary: This article fills the knowledge gap on the relationship between racialised whiteness and migrants' residential decisions in England by analyzing the narratives of 41 Polish migrants. The study reveals that race influenced their residential decisions through reliance on stereotypes and racialization of their whiteness by other residents, leading to complex spatial strategies of inclusion and exclusion. These findings have significant implications for policymakers, emphasizing the importance of creating more inclusive spaces between migrants and existing residents.

Summary: High-income countries still have coverage gaps in the universal health coverage (UHC) due to formal policies and informal barriers. In England, although there is a user fee exemption for mental health treatment, asylum seekers and undocumented migrants are often excluded by both NHS and NGO providers. This study explores the everyday governance of mental health coverage for forced migrants and highlights the rationalities and strategies used by health professionals and bureaucrats in managing the coverage.

Summary: Pathogen infection may drive animal migration, and the infection pattern may be related to migration status. In this study, avian haemosporidian parasites in breeding areas were compared between two species (yellow-rumped flycatcher and Japanese tit) to test the 'migratory exposure' hypothesis. Results showed that the yellow-rumped flycatcher had more diverse parasite lineages, supporting the hypothesis. Nestlings exhibited a similar but more applicable pattern. This study highlights the importance of avian haemosporidian parasite infection patterns in nestlings and provides insights into the driving forces of migration.

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.

Summary: This study explores the perceptions and experiences of refugee migrants regarding a civic orientation course with added health communication. It highlights the positive impact of the course on promoting health and integration, while also indicating the need for adjustments in content and delivery to better suit the migrants' life situations and varying pre-existing knowledge.

Summary: This article examines the economic integration and reintegration outcomes and processes of temporary and permanent migrants in rural-to-urban migration in China. It finds that permanent migrants have higher levels of economic integration and reintegration compared to temporary migrants, and that temporary migrants rely more on individual traits for integration and reintegration. The study provides a comprehensive and dynamic understanding of the integration outcomes and processes of both temporary and permanent migrants.

Summary: Red-headed Buntings use the Earth's magnetic field and other cues for navigation during migration. Weather conditions influence the timing of migration in Red-headed Buntings, but not the direction.

Summary: South Africa's temporary migrant population has been significantly impacted by the COVID-19 pandemic, leading to changes in their employment, livelihoods, and health seeking behavior. The study found that in 2020, compared to 2018-2019, there was a decrease in rural residents initiating migrations and an increase in temporary migrants returning to their rural origin households. Continuing migrants reported fewer job losses compared to rural-stayers, and a significant proportion of return migrants became unemployed in 2020. Additionally, rural-stayers had higher odds of experiencing food shortages in 2020 compared to continuing migrants. Overall, health service utilization decreased in the cohort, with return migrants having lower odds of utilizing health services.

Summary: This study examines the impact of city-level contextual features such as air quality, medical resources, and socioeconomic indicators on intercity migration and the proportion of talented migrants. The results show that air pollution has a strong negative effect, while the availability of medical services has a positive effect on intercity migration. The effects of air quality and medical resources are larger than most socioeconomic indicators, especially for educated migrants.

Summary: In recent decades, India has seen a rapid influx of migrants from agricultural areas to densely populated megacities, which are increasingly vulnerable to climate hazards. There is a need for more attention to be paid to vulnerable new migrants lacking necessary resources when crafting adaptation and mitigation policies.
