The migration for cranes of the new Eastern Flock is way ahead of the larger Western Flock. (Those birds know it's still too cold to arrive in Canada). But at least 29 Whoopers have migrated back to Wisconsin, and there's big news (see Tom's report, next) about the First Family's chick, W1-06 — whom Mrs. Trout's class has nicknamed "Wild One."

Only 10 birds, all in Florida, were confirmed remaining on wintering areas at the end of the week. Of the hatch year (HY) 2006 birds, only 615 is not yet underway, and #533 has gone to Michigan! Crane #309 is another one to watch. She has never found her way back to Wisconsin on spring migration. She left with #407 on March 19 and trackers are concerned that she might venture east again, as she's done in the past.

Until trackers can see the birds' bands or pick up radio signals, it is impossible to identify which bird is where. Tracking reports come weekly and life story pages are updated for Spring 2007 as information arrives. As locations are reported or confirmed, the migration progress of both flocks appears live on our MapServer!

Tom Stehn's report

A very unusual crane in flocks on the Platte River in Nebraska is making is even tougher to identify Whooping Cranes among the migrating birds. Find out why! How DO you know a Whooper in flight? Tom teaches us more, and tells us about those first-year youngsters who must soon leave Mom and Dad for life on their own.

Journal: Why Arrive Early?
The Finish Line >>

See The Finish Line. Compare the arrival dates with the ages of the cranes that have arrived so far.

  • (A) Is there any correlation between the birds' ages and the dates they finish migration?
  • (B) for Bonus: Why might it be an advantage for older cranes to arrive sooner on the nesting grounds?
