NOTES:

  • The flock started with 15 birds but only 13 were delivered to Florida by the ultralights. (Chick #406 died on Day 63 of the migration; Chick #418 was left behind due to feather problems, and he later followed some older ultrawhoopers to find his way.)
  • Chick #418 was left behind when the ultralights and his 14 flockmates left on migration. He had problems with his feathers so wasn't ready to migrate. Instead, he became the first young whooper for supplemental migration--a chick conditioned behind the ultralight aircraft but then put with older birds to see if he could learn the migration route.
  • Only 7 launched with the trike on Day 1. Others were crated and trucked to the first stopover site.
  • Day 4 was the first time all 14 birds went the distance by AIR.
  • On Oct. 24, the two youngest (419 and 420) and the usual trouble maker, #414, had to be caught, crated, and driven to the LaSalle Cty, IL site when they dropped out.
  • Morgan County, IN was the 8th stop and only the 2nd time that the ground crew didn't have to pick up any dropouts.
  • They had some long weather delays. The longest were 7 days in Green County, WI and 7 days in Meigs County, TN (Hiwassee State Wildlife Area).
  • They searched for more than 8 hours before finding and retrieving runaway crane #412 on Day 48.
  • The first air pickup took place Nov. 7, Day 29.
  • An air drop took place Nov. 8, Day 30, under unusual landing conditions.
  • They skipped three stops in Georgia in one day. Flying was good and they just kept going.
  • Crane #406 died at migration stopover 20 (Gilchrist County, FL) due to health problems.
  • They made 21 stops, including the final one at Chassahowitzka.
  • Total flying time for the migration was 33 hours and 11 minutes.
