Abstract: The present invention belongs to the field of devices to scare away birds in general, preferably gulls, pigeons and vultures using a variable electromagnetic field. More specifically, the invention teaches a system of bird repellence by sensorineural interaction, which works through the formation of an electromagnetic field. The system consists of a pulse generator (1) that is electrically connected to a mesh (2) consisting of a plurality of coils (4) arranged in insulating plugs (22) that induce an electromagnetic field that interacts with the birds' magnetic orientation system.
