Research led by scientists from the University of Wyoming and the Max Planck Institute of Animal Behavior shows that migrating animals refine their behavior as they get older. Genetics and social behavior are important factors shaping animal migrations, but information gained through individual experience also appears to help shape migratory movements. The migration findings appear today (March 4) in Proceedings of the National Academy of Sciences, one of the world’s most prestigious scientific journals covering the biological, physical and social sciences.
