What ancestral breeding ground in northern Canada historically hosted the primary migratory flock of Whooping Cranes?

Answer

Wood Buffalo National Park

The Whooping Crane's historical migration spanned vast distances across the North American continent, requiring precise genetic memory regarding key locations. The main migratory segment of the population followed established routes between their northern breeding territories and southern wintering grounds. Historically, the primary breeding location for this migratory flock was situated within Wood Buffalo National Park, which is located in northern Canada. This fidelity to specific ancestral sites underscores the deep evolutionary requirement for intact habitat chains across thousands of miles.
