The Bird Turning Itself into the Wind
One wing dropped to leeward and the tail feather to windward swing it round quickly
The note explains how a bird already carried on the wind can turn sharply toward that wind: it drops one wing to leeward while presenting its tail-feather to windward, so the wind striking the tail swings the body around all the faster. A small pen sketch of a bird seen from behind, wings outstretched with streaming hatch-lines of wind, sits in the upper-right corner.

Turning quickly into the wind
A bird in motion on the wind that wishes to turn sharply toward it goes to leeward with the wing turned to the wind, and to windward with the tail-feather turned to the wind. The wind striking the tail then swings the bird round much more quickly.
Sketch of a wind-borne bird
In the upper right a bird is drawn from behind with wings outstretched, hatched lines trailing from one wing to suggest the streaming wind that carries and turns it. No further transcribed text accompanies the drawing.
