The leader of the ultra-light team accompanying a group of young whooping cranes to Florida says he hopes to arrive in St. Marks National Wildlife Refuge by Christmas. The half-dozen cranes are the 12th group to take part in the ongoing project by the Whooping Crane Eastern Partnership. Two ultra-lights are leading the cranes on the long flight. They left September 28th from the White River Marsh State Wildlife Area in Green Lake County. They were grounded by high winds earlier this week in Illinois.
