Seventeen will be led by ultralight to Florida, and 10 are scheduled to be released with other wild cranes in central Wisconsin. The 5 whooping crane breeding facilities (Patuxent Wildlife Research Center, International Crane Foundation, Calgary Zoo, San Antonio Zoo, and Species Survival Center in New Orleans) all either provided eggs or hatched and raised chicks in 2007. Two eggs came from a wild nest in Florida and 2 eggs came from wild nests in Wisconsin.
