Method and system for preservation against pesky birds and pest animals

A method of permanently eliminating pesky birds from a site having a given surface area, said method comprising:

• a) a dislodging phase comprising the following steps:
• (1) installing at least two bird frightening devices on the site, said devices being selected from the group consisting of rotating-hunters and falcon-imitators, the number of said devices installed on the site depending on the kind of site and the surface area of the site, and
• (2) intensive action of said bird frightening devices and emission of gunshot blast sounds for a duration of approximately one hour to dislodge said pesky birds residing on or near to the site, the bird frightening devices each being set to emit at least one detonation every 1.5 minutes,
• b) a dissuasion phase, following the dislodging phase, to dissuade the pesky birds from returning to the site, said dissuasion phase comprising the following steps:
• (1) cleaning of the site including removal of any nest present on the site, and
• (2) active action of said bird frightening devices for at least one day, said active action being less severe than the intensive action of the dislodging phase a), the bird frightening devices each being set to emit one detonation per three minutes at least;
• and
• c) a controlling phase, following the dissuasion phase, to permanently prevent a bird from settling on the site, the controlling phase including a continuous action of said bird frightening devices whereby each device is set to emit 1 to 40 detonations per hour.
