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. |

Despite
11 nests, no
wild-born chicks hatched in summer 2008. |
