| 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.

| This will require some robotic preening functionality too.
