Zebras follow their memory when migrating
(WorldNews Environment)

Zebras may use memory to guide their migration each year. Memory based on past average conditions provides a clear signal that best directs zebras to their destination. In contrast, current vegetation conditions along the way are less important for the direction of the migration according to a computer simulation. The study highlights that migration routes of large terrestrial mammals such as zebras could be more inflexible than previously thought. ......
