Eastern Flock: With the touchdown of #509 on May 4, an estimated 52 of the 57 Whooping Cranes are home at the Finish Line! Cranes #516 and DAR 27-06 are still migrating. Crane #309 remains in New York, and #318 and DAR 33-05 are in Michigan. Again, no new nesting activity was recorded during the week. Keep up with your favorite crane in the new flock on Life story pages. We update them as information arrives. (Scroll down to "Spring 2007" at the bottom of the page).

Western Flock: Many of the breeding pairs are now incubating their eggs on the nesting grounds in Canada! It's noteworthy that a few are dawdling — or veering east of the typical flyway: there've been two confirmed sightings in Minnesota and one in extreme SE North Dakota, plus 3 mysterious sightings of a crane along the north shore of Lake Erie in Ontario. The rest are busy minding their own business. Now it's time to think about the future chicks, so let's dig in!

Chick Chat: Summer Adventures Coming

Slide Show Handout >>

The chick-rearing building in Maryland is buzzing with excitement. Operation Migration requested 20 to 24 chicks for its next ultralight-led flock, and they're up to eight!

These little fluff balls have an exciting summer ahead. They have much to learn before they fly south this fall — with an ultralight airplane leading the way. Here's a preview of their summer adventures. Use our handout to write your own photo captions! >>

Tom's Report: Great Escape and Traveling Eggs See Tom's Report >>

"If I'm able to fly next week, I would expect to find between 0 and 4 cranes at Aransas NWR," writes Tom Stehn from the main flock's wintering grounds. He wonders why two Whoopers would still be in Kansas when they should be in Canada. Tom also tells us about an exciting "egg hand-off" that took place May 10 at two airports! >>
