The differents species of birds dealt with

Cormorant (Phalacrocorax carbo) :
It is possible to optically scare cormorants up to a distance of 2.5km by specific and direct laser action on the dormitories in order to provoke the mass desertion of the birds using DESMAN laser model FL_R_005 . These devices only project a laser beam without bullet or shot. Its application is silent and causes no environmental disturbance. The optical method of cormorant scaring was developed in France by DESMAN and is commonly applied in other countries.
The optical scaring of cormorants is provoked by the perception by the bird of a high contrast between the luminosity of the surroundings and the red laser beam or its image which are projected in the direction of the bird by the user in the required luminosity conditions. Efficiency is maximal between dusk and dawn as well as in cloudy weather conditions. Use in high surrounding luminosity is not efficient.

Mains advantages: very high efficiency with appropriate luminosity threshold, large range, ease of use, no sound or other nuisance. No habituation. The dormitories are emptied to the extent of 90% after an intervention of a few days.

Potential users: Fish-farmers, persons concerned with the exploitation of ponds, fish federations, various administartions, private individuals.

Starling (Sturnus vulgaris):
The optical method of scaring starlings allows direct action on urban or rural dormitories and the mass desertion of the birds. It uses model FL_R_005 DESMAN laser and model OLM_R_005 laser tools which only project a laser beam without gunpowder, bullets or shot. Their use is silent and does not provoke any disturbance to the immediate surroundings. This method was developed in France and is commonly applied in Italy and Spain on urban or industrial dormitories with a recorded initial population of greater than 100,000 birds.
For applications on urban starling dormitories, operators are trained, on the site where it is to be applied, by DESMAN, inventor of the technique.
The scaring-away is provoked by the perception by the starling of a high contrast between the luminosity of the surroundings and the red laser beam or its image which are projected in the direction of the bird by the user. Efficiency is maximal between dusk and dawn as well as in cloudy weather conditions. Use in high surrounding luminosity is not efficient.

Main advantages: very high efficiency with appropriate luminosity threshold, large range, ease of use, no sound nuisance.

Potential users:
- towns and cities faced with problems of urban starling dormitories : noise and dirt in those streets, avenues, squares and public gardens where the birds have settled,
- town and villages harbouring rural dormitories : excessive concentration of damage-causing birds,
- farmer's federations : widespread crop damage,
- industrial companies : damage to painting and corrosion of installations,
- private individuals : noise and dirt.

Woodpigeon (Columba palumbus):
The opticaly method of scaring pigeons allows direct action on urban or rural dormitories and the desertion of the birds. It uses FL_R_005 DESMAN laser devices and OLM_R_005 handheld laser tools which only project a laser beam without gunpower, bullets or shot. Their use is silent and does not provoke any disturbance to the immediate surroundings. This method was developed in France and is commonly applied in other countries on urban or industrial sites.
For applications on certain urban sites, operators are trained on site by DESMAN, inventor of the technique.
The scaring-away is provoked by the perception by the bird of a high contrats between the luminosity of the surroundings and the red laser beam or its image which are projected in the direction of the bird by the user. Efficiency is maximal between dusk and dawn as well as in cloudy weather conditions. Use in high surrounding luminosity is not efficient.

Main advantages: very high efficiency with appropriate luminosity threshold, large range, ease of use, no sound nuisance.

Potential users:
- towns and cities faced with the problems of pigeons : dirt in those streets, avenues, squares and public gardens where the birds have settled,
- industrial compagnies : droppings, damage to painting and corrosion of installations,
- private individuals: dirt.

Herring gull (Larus argentatus):
It is possible to optically scare up Herring gulls to a distance of 2.5km by specific and direct laser action on the birds in order to provoke their flight using DESMAN laser model FL_R_005 laser or model PRLM_R/R_001 multiple-source laser projectors. These devices only project a laser beam without bullet or shot. Its application is silent and causes no environmental disturbance. The optical method of bird scaring was developed in France by DESMAN and is commonly applied in other countries.
The scaring-away is provoked by the perception by the herring gull of a high contrast between the luminosity of the surroundings and the red laser beam or its image which are projected in the direction of the bird by the user. Efficiency is maximal between dusk and dawn as well as in cloudy weather conditions. Use in high surroundings is not efficient.

Main advantages : very high efficiency with appropriate luminosity threshold, large range, ease of use, no sound nuisance.

Potential users:
- towns and cities faced with problems of noise and dirt of these birds,
- industrial sites for which the presence of the birds is costly and undesirable particulary on roofs and product storage sites.

Rook (Corvus frugilegus) :
It is possible to optically scare rooks up to a distance of 2.5km by specific and direct laser action on the rookeries in order to provoke the mass desertion of the birds using model FL_R_005 DESMAN laser. These devices only project a laser beam without bullets or shot. Its application on the dormitories is silent and causes no environmental disturbance. The optical method of bird scaring was developed in France by DESMAN and is commonly applied in other countries.
The optical scaring of rooks is provoked by the perception by the bird of a high contrast between the luminosity of the surroundings and the red laser beam or its image which are projected in the direction of the bird by the user in the required luminosity conditions. Efficiency is maximal between dusk and dawn as well as in cloudy weather conditions. Use in high surrounding luminosity is not efficient.

Main advantages : very high efficiency with appropriate luminosity threshold, large range, ease of use, no sound or other nuisance. No habituation.

Potential users:
- towns and cities faced with rook problems : noise and dirt in those streets, avenues, squares and public gardens where the birds have settled,
- industrial companies : noise, droppings and corrosion of installations,
- private individuals: noise, dirt.
