This creation system provides a kind of structure-improved of scarer, is a kind of scarer being made of parts such as pedestal, power device, drive rod, two bird-scaring units and two balance weights, drives bird-scaring unit bird repellent using wind-force or motor； One infrared detector can be also set on the shaft of motor, with detect birds it is close when, issue the sound of bird repellent； Also bird person can be driven with the sunlight of refraction by the reflecting piece on bird-scaring unit.本創作係提供一種驅鳥裝置之改良結構，係一種由底座、動力裝置、傳動桿、二驅鳥器及二平衡塊等零件所組成之驅鳥裝置，利用風力或馬達帶動驅鳥器驅鳥；亦可在馬達之軸桿上設置一紅外線偵測器，以偵測到鳥類接近時，發出驅鳥的聲響；亦可藉由驅鳥器上之反光片，以折射的太陽光來驅趕鳥者。
