A deer hunting decoy has a central post within a flexible cover having front and rear faces with coloration simulating the hind quarters of a deer, with each including a lighter colored central portion surrounded by a darker colored border. The lighter colored central portions are covered by tail flaps. The tail flaps are joined for rotational movement to an axle that extends across the central post and through holes in the flexible cover. A pull cord is directly or indirectly joined to the axle. Tugging the pull cord causes rotation of the axle and movement of the tail flaps to simulate tail movement of a deer. The central post is staked to a ground. Different decoy deer heads are interchangeably attachable. A buck head silhouette terminates in a tube connector that releasable fits within a proximal end of the central post. A grazing doe silhouette has a hook portion at one end and a doe head at the opposite end. The hook portion is inserted over an edge of an opening in the flexible cover and the head portion is pinned to the ground.
