Nature Ecology & Evolution - Combining 27 years of citizen science data with whole-genome sequencing, the authors show that mass mortality of purple martins caused by a severe winter...

With rapid environmental change, shifts in migration timing are vitally important for population stability in migratory species and have been widely documented. However, little remains known about how...

Abstract Endothermy is an energetically expensive trait, yet it has posed an evolutionary advantage across different lineages—a paradox that remains puzzling to biologists. Here, I investigate whether...

A warming climate is affecting the phenology of life on earth, including when birds migrate and start breeding. We show that earlier arrival is a general pattern also for birds travelling to the Arct...

The Global Flyway Network (GFN) is a partnership between researchers worldwide who are devoted to long term – usually demographic – work on long distance migrating shorebirds.
