Learn to migrate by following their parents

Group 3 chicks are wild-born. Their parents raise them and teach them to migrate. This is the natural way cranes learn to migrate. One day, the flock will be large enough for wild-born parents to take over. Then human-assisted migration will no longer be needed. Scientists hope to reach their goal of 25 breeding pairs from 125 birds in Wisconsin by 2020.
