Group 2

Learn to migrate by following older cranes in the flock

Group 2 chicks are also captive-born. In fall the chicks are released in the company of older cranes from whom the young birds learn the migration route in a program called
Direct Autumn Release (DAR).

On July 20, the 11 chicks for Direct Autumn Release (DAR) arrived at Necedah NWR from nearby International Crane Foundation (ICF). They were released Oct. 25 with wild cranes.

Group 3 (W = wild hatched)

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, this flock will be large enough for wild-born parents to take over. Then human-assisted migration will no longer be needed.

Parents #309 and #403 with chick W1-10 on July 7, 2010. Seven chicks hatched in 2010 in the Wisconsin wild. This was the largest number to hatch in the new flock's history. Wild-hatched chicks face many dangers in the first weeks of their lives, and by summer's end only W1-10 and W3-10 survived.They were flying by the end of August and better able to escape predators.
