Experience drives innovation of new migration patterns of whooping cranes in response to global change

Animal migration patterns are changing in response to changes in climate and land use, and these changes could be important for survival of migratory species. These changes, which are adaptations to a changing environment, can happen very quickly, but so far studies have focused on evolutionary changes, which may be too slow to be effective in a rapidly changing world. We used long-term monitoring data of whooping cranes to show that migration patterns can change within an individual’s life and, further, that these changes are initiated by older, experienced birds and then spread to younger birds. This results suggests that maintaining older individuals in a population may be important for effective behavioral adaptation to changing environments.
