The first cranes were able to fly north faster than south because they knew where they were going. As the cranes flew south, they memorized the landmarks and the routes they took. They stopped more going south because they were new to the area. When migrating north, the weather is better permitting the cranes to migrate more quickly. There is also more food in the spring, giving the cranes the energy to travel. Finally, an obvious reason, some cranes left earlier, so they got back home sooner.
