Abstract: There is provided a deer tail decoy which simulates the communicating and motion characteristics of a deer's tail. The decoy includes flexible and paired front and rear tail-shaped light colored background and dark inlaid materials, each of which is frayed or slit about their peripheral margins to provide contrasting inner and outer flaps which flutter in the wind. The top section of the decoy includes a rigid support such as a wire so as to permit the decoy to flag in the wind. When secured to a mounting site with a cord or wire, the wind blown deer tail decoy partially rotates about the wire, swings as a pendulum, ripples through its entire fabric structure and creates contrasting fluttering and flapping in the wind so as to emulate a deer's tail in motion.
