Our captive Whooping Cranes are laying eggs and wild cranes are building nests and incubating – breeding season is here!
A tradition at the International Crane Foundation is to follow our “Egg Score Card,” which tracks the Whooping Crane eggs from our captive flock and wild nests in Wisconsin.

Wild Whooping Crane nests in Wisconsin (4/20/17)
Note: Each crane is identified by a two-part number, with the second number identifying the hatch year. A “W” indicates that the crane was hatched in the wild.
Earlier this week 27 eggs were collected from active nests in central Wisconsin, as part of a management effort to encourage the cranes to lay a later, second clutch of eggs. The eggs were transferred to our headquarters, and after examining each egg we determined that 26 are fertile! The fertile eggs will be transferred to our partners at the Patuxent Wildlife Research Center in Maryland for hatching.
