Where Are They Now? All Is Quiet on the Wintering Grounds NEWS FLASH! After this report was posted, a sighting of pair #415 and mate #505 in Indiana announce that spring migration is starting! This pair wintered in TN, so they're clearly on their way back to Wisconsin.

The Western (natural) flock's estimated 266 cranes are still wintering in Texas. That will soon change!

The Eastern Flock's estimated 87 cranes are still overwintering in these states. Three "early birds" are likely migrating.

Western Flock News>>
What important discovery was made this week at Aransas NWR? Why is Tom Stehn taking this wild juvenile to the vet?

"We've been through these bad winters before. The strong ones will tough it out and pass their genes on."

—Tom Stehn

Eastern Flock News>>
Winter monitor Bev tells another great bedtime story about the crane-kids at St. Marks. (Next time: news about the crane-kids at Chass.)

In Texas with the Western (natural) flock, Tom Stehn tells status and stories of the whoopers he's observed for over 30 years. In Florida watching over the Class of 2008 are Sara, Eva, Brooke and Bev. They share photos, crane mischief, and news from the two Florida release sites.

Read the map title and legend below. Locate the main wintering grounds of the Eastern flock and the Western flock. (Also see: A Closer Look.)

 


  • What things does good habitat provide? How do you think habitat conditions on the wintering grounds will affect (1) crane numbers and (2) the number of chicks that will hatch on the nesting grounds this summer?

Smart and Safe: Q and A With Tom Stehn

Last week Tom Stehn asked you to think about the two questions below. How do his answers compare to your ideas?

Q.How do whooping cranes stay safe from predators when they are sleeping at night?
A. Whooping cranes always spend the night standing in shallow water out in the open. That way, no predator can approach the sleeping cranes without making noise splashing through the water and waking the cranes up.


Q. How would a whooping crane be able to fight off something as
big as a coyote?

A. The whooping crane is very fast and has a very strong beak. There is a documented record of a whooping crane killing a coyote by striking it in the head. Whenever I see coyotes get close to whooping cranes, the cranes get very alarmed, raise up to their full 5-foot height, whoop loudly, and look very threatening. The coyote always looks for a few seconds and then wisely decides to slink off without approaching the cranes.

Coming Soon: Track the Migration
With the help of trackers' reports , you'll see the migration progress of both flocks — ALL the world's migratory Whooping cranes — live on our MapServer starting in March.
