Class of 2008: Everybirdy's Headed Home

Map and Track >>

The Chass release site in Florida is empty! Juveniles #803, 824, and 827, the three that stayed behind when their four classmates left on March 24, began migration April 4. All of the Class of 2008 is headed to Wisconsin, where some of the adult crane pairs are already nesting! After the wonder of migration, everyone hopes the next miracle will be baby chicks!

Western Flock News>>
Over half the flock has begun migration from Texas. Will conditions be better for them when the cranes reach Canada? Tom Stehn and Brian Johns report from both ends of the migration trail. >>

The Finish Line >>

How many Whooping cranes from the Eastern flock are back in Wisconsin? Count them at the Finish Line. Over half of the wild cranes of the Western flock are now in the Central Flyway. See the latest migration map! >>

Eastern Flock News>>
Sara shares the latest news on the migrating Class of 2008 as well as the Wisconsin arrivals. This very busy week brought both good news (8 nests confirmed!) and bad news (two losses). Find out more: >>

Journal Topic: Nesting! Calculate and Compare: >>

Already 8 nests hold the promise of new chicks. Dig into our chart to answer this week's questions:

  • View the chart and calculate: When might the each nest hatch if the cranes nest successfully?
  • If you were a scientist who could focus a Web cam on the crane nests in Wisconsin, what would you watch for? What would you hope to learn? (Before answering, see the link to the 2008 nesting summary. >>)
  • What would you need to know in order to make a prediction about this year's nesting success in the Eastern flock? In the Western flock?

Slide Show: Meet Al and Diane

Slide Show >> 

Female cranes tend to be picky in their choice of a mate. Unless they meet a compatible male, female cranes will not lay eggs. This makes sense because crane pairs work as a team. Together they share all the duties: defending the territory, building the nest, incubating the eggs, and raising the chicks.

Tom Stehn tells us about a remarkable crane pair in the natural flock that has brought more chicks to Aransas than any crane pair ever. How many chicks? How often? How did this pair come to be called Al and Diane? From Tom's rich memories and knowledge of the flock come great stories. You'll like this one: Meet Al and Diane!
