This study shows climate warming reduces the energy benefit of long-distance migration in birds by lowering winter thermoregulation costs, favoring shorter migrations.

This paper uses genetic data to determine the origin of vagrant yellow-browed warblers in Europe, finding they originate from central Siberia, suggesting mass misorientation.

The study examines how wing morphology and plumage color influence crossing strategies of ecological barriers in migratory birds, finding differences in flight altitude across barrier types and traits affecting flight behavior.
