Fly without flapping? Andean condors surf air 99% of time
WASHINGTON (AP) — A new study sheds light on just how efficiently the world’s largest soaring bird rides air currents to stay aloft for hours without flapping its wings.
The Andean condor has a wingspan stretching to 10 feet and weighs up to 33 pounds.
A study published Monday in the journal Proceedings of the National Academy of Sciences showed that these birds spent just 1% of their time aloft flapping their wings, mostly during take-off.
One condor flew more than five hours and covered more than 100 miles without flapping its wings.
