Fun facts

  • Overhunting destroyed its traditional southward migration routes, and today almost the whole continental population winters in Greater Yellowstone regardless of where it breeds in summer.
  • It has been translocated from the Red Rock Lakes refuge in Montana to other national refuges to restore its historic distribution.
  • It has no recognised subspecies.
