I once watched a small falcon trying to prey on a flock of pigeons. It
literally hung in the air without
beating it's wings at all by facing into the wind
Facing into the wind will not help the animal to maintain altitude.
Something else must have been going on as well, in order to provide energy
for hovering at constant altitude.
