Climate warming reduces the energetic advantage of long-distance migration in a migratory bird

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

The road to nowhere: geolocation-by-genotype traces large-scale yellow-browed warbler vagrancy to central Siberia

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.

Crossing strategies of ecological barriers are affected by wing morphology and plumage colour in small migratory birds

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.
