A wind activated decoy has a silhouette body with a wing support therethrough. Opposite first and second wings are secured to respective wing spars, with one spar being removably installable through the support. The second wing attaches removably to the first spar after installation through the support. Each wing comprises a thin, rigid sheet with a sinusoidal cross section to catch the wind and cause the panels to rotate. The chords of the two panels have an angular displacement of forty five degrees, to avoid any singularity and provide continuously unequal aerodynamic forces upon the panels to produce continuous rotation in a breeze. The panels are marked differently on opposite surfaces and when rotated, simulate the flashing of a bird's wings when the bird is alighting. A support column extends from the body and is removably installable in a tubular support, allowing the decoy to pivot freely into the wind.
