Sometimes the breeding and wintering regions overlap. In such cases, birds that have nested farther north displace the birds in the overlapped area for the winter, thus creating a false impression of a sedentary mode of existence. This type of migration characterizes crows. ...

As such, omnivorous and carnivorous birds using aquatic habitats may be more affected by environmental changes that alter their diet and range. Even though there were no overall differences in their ecology and life history compared with non-migrators, migratory bird species still harboured a more...

Millions of migratory birds occupy seasonally favourable breeding grounds in the Arctic1, but we know little about the formation, maintenance and future of the migration routes of Arctic birds and the genetic determinants of migratory distance. Here we established a continental-scale migration system ...
Climate change is forcing the redistribution of life on Earth at an unprecedented velocity1,2. Migratory birds are thought to help plants to track climate change through long-distance seed dispersal3,4. However, seeds may be consistently dispersed toward
Whether long-distance animal migration facilitates or hampers pathogen transmission depends on how infections affect the routes and timing of migrating hosts. In aJournal of Zoologystudy, investigators have found that haemosporidians—blood parasites commonly infecting birds—likely impede migratory performa...
