Abstract: Birds trouble has been one of the prime problems resulting in enormous losses to agriculture in recent years.Although some necessary measures have been put into operation，however，such measures often have limitations on scope，cost hard labors，and probably cause harm to ecological balance and even endanger the safety of food.Moreover，most of traditional birdrepellers cannot repel the birds movably，and easily be adapted by birds and need frequent maintenance.Therefore，in order to avoid the above-mentioned disadvantages，a movable automatic flying repeller was developed in this work，which was integrated with multiple measures.The repeller took advantage of the birds’fear for human beings and their natural enemy.Techniques of bionics，computer，electronics，and UAV were employed to obtain the solution，preventing birds from adaptation，which has not been solved by traditional measures.
