On fledging, the young cranes are conditioned to follow an aircraft on a 1,250-mile route between Wisconsin and a coastal reserve in Florida. In the trial spring of 2002 all of the plane-led whoopers found their own way back to the Wisconsin natal area. In subsequent years more plane-led cranes have been introduced to this new fly-way and in 2006 the hand-reared birds (known as ‘ultracranes’ after their ultra-light aircraft guides) successfully bred for the first time.
