Device for preventing the perching and nesting of birds, characterised in that it is comprised by a geared motor which, supplied by various energy sources, operates one or more rods connected to it, performing a controlled rotation by means of programming or by laser motion detection in places where birds are to be prevented from settling, as the rods, on performing the rotation or sweep, form a moving rejection member that does not harm birds but bothers them sufficiently for them to fly off when they become aware of the rod touching them. The invention presented herein offers the advantage of protecting a building in its entirety, preventing birds in general from settling on roofs, cornices, gutters, terraces, aerials, bell towers and electricity pylons.
