Whooping
Crane Total Population
*Until the next updating of Total Populations on this page, every known death in the Eastern migratory flock is reported here. *The 265 cranes above is an estimate. Forty-one chicks fledged from a record 66 nests in 2008. Approximately 38 chicks arrived at Aransas in fall 2008, with the peak flock size estimated to have been 270. An estimated five whooping cranes have died at Aransas subsequent to completing the fall migration. **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) either provided eggs or hatched and raised chicks in 2008. Four eggs came from abandoned wild nests in Wisconsin and successfully hatched at Patuxent. Twenty-one chicks were raised for the release programs in central Wisconsin (14 ultralight, 7 direct autumn release). One direct autumn release chick was killed by a predator on November 6, 2008 at Necedah NWR. **Three of these young are genetic holdbacks and will remain in captivity as future breeding stock. The table does not reflect captive young that have entered reintroduction programs in 2008.
