Whooping cranes have been known to fly for 10 hours, covering distances of up to 750 kilometers! They use a special combination of spiraling and gliding that keeps their energy usage to a minimum. If you’ve never seen a whooping crane in flight, look up at the sky and keep your eyes peeled because they are making a come back. Although these birds are endangered, their populations have been climbing since 1967 in part because of conservation efforts in Canadian and America. If you don’t have time to sit watching the skies all day, check out this video showing these beautiful birds in flight.
