Western Flock: The migration sightings now are mainly in Canada, and Wood Buffalo National Park will soon be an active nesting grounds. While some Whooping Cranes are already sitting on nests there, at least two cranes haven't even started migration from Texas! Eastern Flock: The first babies for the Class of 2008 have hatched, and with the touchdown of #733 on May 7, all but one (#727) in the Class of 2007 is home! The six 2007 DAR birds are in Michigan. Most of the flock's 72 birds are where they'll be for summer, but #516 hasn't begun migration yet. |

Western Flock Reports: Brian Johns prepares for nesting surveys next week. What does he hope to find? >> One or two stragglers remain in Texas, and Tom Stehn helps us understand why.>> Eastern Flock Report: This would have been the week for 3 nests to hatch young, but all 10 spring nests have now been abandoned. Sara shares that sad news but also has glad news to end the season's reports. There's reason to hope. >> |

Now you have read the field reports about the failed nests. Tom Stehn says, "Re-nesting is possible, but usually occurs after a pair's nest has been harmed by something like a flood or predator. It is really hard to say what the whooping cranes will do that may have left their nests for no reason apparent to us." Operation Migration's Liz Condie puzzled, "Is it weather related? What is going on? If only there really was a Dr. Doolittle." Join our scientists in grappling to answer:
- Why did the Whooping Cranes leave their eggs? What factors could you investigate and track?
"It
is very, very hard to successfully get Whooping Cranes to breed," Tom
Stehn reminded us last
week. Sadly, this week's nest report proves it: All nests failed.
Whoopee! The first chick in the new Class of 2008 has hatched! Chick #801 emerged on May 4, soon followed by #802 and #803. We've started "Baby Books" for each precious fluff ball so you can meet them right away. Operation Migration's Bev and ultralight pilot Brooke are in Maryland for care and training of the chicks before they are transported to Wisconsin for flight school in June and July.
More eggs will be received for hatching soon at Patuxent WRC. Will the Class of 2008 have 24 chicks, as hoped for?
Last week we answered: Where do the eggs for the new flock come from? You learned that the eggs are laid by Whooping Cranes living at 5 captive breeding centers. Next question: Where did the eggs to start the captive breeding centers come from?
The fascinating story starts with big discovery — and then a helicopter, a wool sock and a bucket of water. Join Canada's Brian Johns as he shares the story of The Big Egg Hunt and how it's helping to save the species. >>
