Which chicks are these? In September the chicks of cohorts 2 and 3 began training together. Pilot Brooke Pennypacker is flying the ultralight. He is leading the chicks over the Wisconsin refuge that will always be their summer home. They must get to know the landscape they will come back to next spring.   Photo Heather Ray Journey North is pleased to feature this educational adventure made possible by the Whooping Crane Eastern Partnership (WCEP).
