PROBLEM TO BE SOLVED: To provide a means for eliminating damage by preventing flying-in of gray starlings and harmful birds on roadside trees except for felling.SOLUTION: To achieve the solution of problems such as temporary damage and impairment of a landscape, an apparatus for preventing flying-in of harmful birds is constituted by installing vibration generators which are main vibrators and sub-vibrators, and sound collectors on a tree and branches. The vibrators are operated by signals from the sound collectors, and sound generator sound collectors react to chirping of gray starlings and harmful birds and cause micro quake to impede flying-in of harmful birds.COPYRIGHT: (C)2013,JPO&INPIT【課題】街路樹におけるムクドリ、害鳥の飛来防止被害を伐採以外でなくす手段がなかった。【解決手段】一時的な被害や景観を損ねる等の問題点を解決達成するために、メイン振動装置とサブ振動装置である加震器及び集声器を樹木と枝に据え付ける。その振動装置は、集音器の信号で作動し、音声発生装置集音器は、ムクドリ、害鳥の鳴き声に反応し微震動をおこし阻止する有害鳥類飛来防止装置である。【選択図】図1
