NOTES:

  • In a first-ever decision, a bird (Crane #810) was removed from the migration roster because his aggression is a risk to the other birds. He was released with the other Direct Autumn Release (DAR) chicks and was renamed #10-08. He migrated successfully with older birds leading the way.
  • The entire group did not fly together for the first time until October 10.
  • This was the latest departure on the calendar, but the earliest departure if you count it by the age of the youngest bird (124 days of age).
  • They had 11 days of weather delays in Green County, Wisconsin.
  • In one of Alabama's rainiest autumns in history, the team decided to break the migration and go home to families for the holidays. On Dec. 31 the migration was still underway, grounded by weather in Chilton County Alabama. For the second year in a row, the fall migration goes into a new calendar year.
  • Crane #804 didn't want to land at the Chass pen! The pilot had to lead him to a landing 9 miles away. Then he was boxed to ride on an airboat to the remote island where the release pen is.
