Western Flock: They're off to Canada! In his flight over the refuge to count cranes yesterday, Tom Stehn found just 34 whoopers!

Eastern Flock: More than half of the new flock's 74 birds (including one HY2007 ultralight-led crane), are confirmed back in central Wisconsin! Topping off the good news, a few of the crane pairs have raised hopes that chicks may finally hatch this summer!

Sara's and trackers' report

Western Flock Report: Seventeen groups of Whooping Cranes have been reported all the way from central Texas to South Dakota, with most sightings from Kansas and Nebraska. The cranes now as far north as Nebraska will be held up by a snowstorm and unfavorable winds in that state over the next few days! Find out why Tom thinks the cranes left earlier this year. Decide if you'd like to do what Tom did today. >>

Eastern Flock Report: Young #709 was first from his class to fly over the refuge, but where is he now? Sara comments on his behavior, and trackers Eva and Anna tell which cranes are where. The First Parents (pair #211 and #217) and their offspring (W601) are sitting on nests! (No one knows yet if eggs have been laid.) >>

Journal Question: How Do They Know When They've Reached Home? Audio Clip: Hear Ultralight Pilot Joe Duff >>

On April 4, #709 became the first of the Class of 2007 to complete migration to Wisconsin — but wait! He overflew and kept going. Read more on his bio page (scroll to the end for latest news) and listen to Joe's audio clip to answer:

  • How do you think #709 will know where and when to settle for the summer?
