Start Over Back More Crane Stories Photo: Operation Migration Over the Treetops Is that YOU watching from the observation deck? The trike is leading these five over to join with flockmates at a different pen site for the first time. How will the birds get along? At first, a fence divides the groups so they can get used to each other without fights. Soon the fence comes down. Chicks mingle face-to-face, working out their pecking order. The costumed handlers use puppets to break up any fights so no one gets hurt. Next they will learn to fly well as one group. Then the young birds will be ready to migrate!
