PROBLEM TO BE SOLVED: To provide a nesting place exploration method and a nesting place exploration system for raptors capable of achieving high accuracy of nesting place identification, achieving efficiency, labor saving and cost reduction of nesting place exploration. SOLUTION: The method for exploring a nesting place of a bird of prey according to the present invention includes (1) a step of capturing a living body of a decoy animal 10 having a moving device 20 in the bird of prey A, and (2) a homing action of the bird of prey A. And a step of causing the bird of prey A to transport the decoy animal 10 to the nesting site B, and the nesting site B is specified based on the position information transmitted by the moving device 20 that has been transported together with the decoy animal 10. .. The raptor nesting site exploration system 1 of the present invention includes a living body of a decoy animal 10, a moving device 20 having a position information transmitting means 23, and an exploring device 40 having a position information receiving means 41. Is held by the decoy animal 10. [Selection diagram] Figure 1【課題】営巣地特定の精度が高く、営巣地探査の効率化、省力化、及び低コスト化を達成可能な、猛禽類の営巣地探査方法及び営巣地探査システムを提供すること。【解決手段】本発明の猛禽類の営巣地探査方法は、（１）移動装置２０を保持させた囮動物１０の生体を猛禽類Ａに捕獲させるステップと、（２）猛禽類Ａの帰巣行動により猛禽類Ａに囮動物１０を営巣地Ｂへ搬送させるステップと、を備え、囮動物１０とともに搬送させた移動装置２０が発信する位置情報に基づいて営巣地Ｂを特定することを特徴とする。本発明の猛禽類の営巣地探査システム１は、囮動物１０の生体と、位置情報発信手段２３を有する移動装置２０と、位置情報受信手段４１を有する探査装置４０と、を備え、移動装置２０を囮動物１０に保持させたことを特徴とする。【選択図】図１
