A decoy mounting and movement system for mounting a hollow animal species decoy and for simulating life-like movement of the animal species between a rest position and a vertically pivoted position which simulates feeding by the animal species having a decoy mounting stake formed of an elongate upper stake section and an elongate lower stake section interconnected via an elongate vertical return spring capable of bending along its length to create an angle between the upper and lower stake sections, the upper stake section dimensioned for insertion into the hollow of the decoy through an opening in its underside in communication with the hollow of the decoy, wherein the fulcrum for vertical pivoting of the decoy is positioned at the lower end of the upper stake section and the ratio D'/D is less than 0.25, wherein D' is the distance between the underside of the decoy and the fulcrum for vertical pivoting, and D is the length of the upper stake section.

The invention claimed is: 1. In a decoy mounting and movement system for mounting a hollow animal species decoy and for simulating life-like movement of the animal species, under the control of a decoy operator, between a rest position and at least two other positions, said decoy having a neck mounted head and a tail at opposite ends of a body, said body having a top side, an underside and an opening in the underside communicating with the hollow in the decoy, said system including: a decoy mounting stake comprising an elongate upper stake section having an upper end, a lower end and a length, and an elongate lower stake section, said elongate upper stake section and said elongate lower stake section being interconnected via an elongate vertical return spring means capable of bending about a fulcrum located intermediate a length of said elongate vertical return spring means to create an angle between the upper and lower stake sections, the lower stake section including ground penetrating means for embedding in the ground to securely support said mounting stake in the ground, said upper stake section dimensioned for insertion into the hollow of said decoy through the opening in its underside, and pin means pivotally securing the top side of the decoy body to the upper end of said upper stake section when the upper stake section is with the hollow of the decoy; elongate rotation return spring means having an upper end and a lower end, said rotation return spring means being both supported at its upper end and extending longitudinally downwardly along said upper stake section from a point below the upper end of the upper stake section, one end of flexible line means being attached to the lower end of sad rotation return spring means, extending downwardly along and generally parallel to said upper stake section and bending around a protrusion mounted on the upper stake section, the other end of said flexible line means being attached to a vertically extending intermediate portion of a formed wire, said formed wire having one end surrounding said upper stake section for allowing rotation of said formed wire thereabout and the other end of said formed wire connected to the underside of said decoy; a control line having one end attached to the neck of the decoy, the other end of the control line passing around a ground mounted pivot means, said pivot means adapted to be positioned under the tail of the decoy in its rest position and offset towards the decoy operator, and controlled by the decoy operator for moving said decoy between its rest and at least two other positions; whereby an application of tension in the control line by the decoy operator initially causes the decoy to rotate about 180° from its rest position about said decoy mounting stake to a second position, which rotation places the rotation return spring under spring tension, and the application of increased tension in the control line by the decoy operator causes the decoy to pivot vertically about said fulcrum into a third position simulating feeding or grazing by the animal species, which vertical pivoting places the vertical return spring under bending and spring tension and, upon release of the tension in the control line, the decoy moves between its third position and its second position and, with continued release of the tension in the control line, moves between its second position and its rest position; the improvement comprising: said fulcrum about which said decoy vertically pivots being located at the lower end of the upper stake section; and wherein a ratio D'/D is less than 0.25, wherein D' is distance between the underside of decoy and said fulcrum about which said decoy vertically pivots, and D is the length of upper stake section. 2. In a decoy mounting and movement system, as claimed in claim 1, wherein the ratio D'/D is in the range 0.15 to 0.2. 3. In a decoy mounting and movement system, as claimed in claim 1, wherein the other end of the control line is secured to a spool and the spool is controlled by the decoy operator. 4. In a decoy mounting and movement system, as claimed in claim 3, wherein the spool is staked to the ground in a manner permitting rotation of the spool about said stake. 5. In a decoy mounting and movement system, as claimed in claim 1, including the protrusion mounted on the upper stake section which engaged the vertically extending intermediate portion of said formed wire in the rest position of said decoy.
