How Are DAR Chicks Prepared for Migration?
DAR chicks are under the care of Marianne Wellington, a chick-rearing specialist, and other helpers. Marianne "hides" in a white costume and raises the chicks with the help of crane puppets.
Chicks fledge when they are around 70 days old. They are allowed to roam freely during the daytime—with frequent checks by Marianne and other costumed "parents." In early fall, they are released on the Wisconsin refuge so they can hang out with older cranes that will soon be migrating. Will these older cranes help the new DAR chicks learn the way to Florida? That's the plan!

• Chicks in the wild learn migration from their parents, so the Direct Autumn Release (DAR) method is getting closer to the ways of nature. Make a 3-column chart to compare (1) the DAR migration to (2) the ultralight-led migration and (3) the free and wild whoopers' migration.
