Which historical breeding areas are cited as being far removed from the current Wood Buffalo National Park site?

Answer

North Dakota and Minnesota

The historical range of the Whooping Crane was significantly wider before extensive human impact. When comparing old range maps to current locations, a massive contraction is evident. Specifically, the historical breeding range used to cover substantial portions of what are now the states of North Dakota and Minnesota. These areas are geographically distant from the current primary breeding site, which is restricted to the remote wetlands of Wood Buffalo National Park in Canada, illustrating how much suitable habitat has been lost, driven primarily by habitat destruction and hunting pressure.
