Tracking a Young Whooper's First Migration (image) University of Maryland Share Print E-Mail Caption This young whooping crane is on its first fall migration, guided by an Operation Migration ultralight. Brown bars on its wings will fade by the time this bird migrates north in spring. Whoopers in the Eastern population have identifying bands, and many carry tracking devices that record their movements in detail. Credit Joe Duff/copyright Operation Migration USA Inc.
