A A record 84 chicks hatched from 65 nests in 2007, and 250+ cranes are expected to arrive at Aransas by early winter, including 45+ juveniles. The number of chicks hatched in Wood Buffalo in 2007 will not be added to population totals in this table until the flock is censused at Aransas in early winter, 2007.
B This number reflects the birds regularly monitored in Florida. A few additional cranes could be
present in unknown locations. One chick fledged in the wild in 2007.
C The 27 chicks were raised in captivity and shipped to the Necedah NWR in central Wisconsin for later reintroduction. 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.

* Numbers are of young remaining at the captive centers after eggs and/or birds were shipped out for reintroduction programs. In most cases, these young are genetically valuable and will become future captive breeding stock.
TOTALS (Wild + Captive) = 355 + 148 = 503
