This video says about itself:

13 July 2016

This Golden Eagle may appear to be floating, but it is actually riding on rising columns of warm air known as thermals. Thermals are generated when the sun warms the earth’s surface, indirectly heating the air closest to the ground, causing it to rise. Soaring birds can use this rising air to gain elevation and remain aloft for extended periods without flapping their wings.
