Highways in the Sky
Photograph by Norbert Rosing
On wings spanning seven feet (two meters), a bald eagle comes in for a landing. Flight can be swift: In Wyoming one migrating adult was clocked at 89 miles (140 kilometers) an hour. On long-distance migrations, the birds use thermals, rising bodies of warm air that let them coast with minimal wing flapping, conserving energy. |
