Andean condor can fly 100 miles without flapping its wings
An Andean condor, one of the largest flying birds on the planet, soared through the air for 100 miles (172 kilometers) and didn't bother with flapping its wings. This epic example of flight comes to us from a team led by researchers at Swansea University in the UK.
The scientists took a deep look at the connection between environmental conditions and the amount of effort large birds put into their flights. To do this, they attached data recorders to Andean condors that allowed them to log every single flap of the wings as well as the birds' flight paths.
