It can be assumed that a change in the strength of the magnetic field which is generated by such a current signal and which results from the strong changes in the current signal particularly disturbs pigeons.
  • the voltage profile of the alternating current can have a triangular shape (sawtooth voltage) or a rectangular shape.
  • the voltage curve can be impressed arbitrarily by modern converter technology in order to generate a signal that is most effective for the birds to be scared away, i.e. has the greatest deterrent effect.

  • the winding 1 is laid at the location from which the pigeons are to be driven out. These are in particular balconies, window sills, roof areas and similar building areas. By feeding a current into the conductor turns 2, 3, 4 of the winding 1, a magnetic field is created in the vicinity of the winding 1, in particular in the area surrounded by the winding 1.
  • the senses of pigeons, which detect the earth's magnetism, are sensitive to this magnetic field. If the area from which the birds are to be kept is too large to generate a sufficiently strong magnetic field with one winding, a plurality of windings 1 can be provided distributed over this area.

  • the sawtooth shape and the rectangular shape an exponentially increasing sawtooth, a trapezoidal shape, a direct current, signals in the form of an isosceles triangle, sinusoidal shape and composite shapes are shown.
  • the signal shape should be selected depending on the sensitivity of the birds to different dynamic magnetic field strength profiles and also depending on the impedance of the winding 1 itself. By combining different pulse shapes, different characteristics of the magnetic field can be realized, which are particularly disturbing for a certain group of birds. This increases the reliability and effectiveness of the device.
