       | But I regularly watch Red-Tailed hawks, around these parts, and
       | they not only change the way they flap their wings, they
       | drastically alter the surface area of their wings; dependent upon
       | the type of flying they are doing. Sort of like ailerons, on
       | airplanes.
       | 
       | For example, when they are "on a mission," going from "here," to
       | "there," they trim their wings, so they are narrow and smooth.
       | They almost look like gulls, in flight.
       | 
       | However, when they are hunting, which involves slow, flapless,
       | soaring, they spread out all their feathers, so their wings have
       | a great deal of surface area.
