Summary:
The term soaring is here applied to the flight of certain large birds which maneuver in the air without moving their wings. Many theories have been evolved and published relative to this mode of flight. Of all those theories the only ones acceptable are those based on the utilization by the bird of the internal energy of the wind. In the particular cases studied, the energy required for the support was supplied by an upward component of the wind.
