BirdLaser is an animal friendly bird hering tool for airports, fish farming, farms, barley, fruit and berries and other locations with bird problems. All our lasers are environmentally friendly and harmless to humans and animals without harmful radiation. Our new 1000mW@1meter diode laser module with a range of 3000 meter is classified as class 4, the laser power is measured out of the laser housing at a distance of 1 meter. We have measured temperatures on the laser spot at a distance of one meter with a thermal camera which shows no effect on temperature rise, this makes it almost impossible to cause eye damage, but glare is still a problem that must be taken into account during use. Even if the safety is better than expected, the laser precautions should be followed.
In comparison the old 500mW laser has an output power of around 200mW, which not is very efficient.
The Swedish Radiation Safety Authority has conducted a study on reported eye injuries over a period from 1999 to 2012 which shows that eye injuries occur from exposure to concentrated laser beams typically with a diameter of around 1-2 mm at a distance of less than 1 meter, this type of laser can burn through clothing, skin and other materials. In our expanded 50 mm laser spot there are no intense beams of this type.
GOOSES AND SWANS
Lasers have proven to be incredibly effective against gooses and swans, our own trials and feedback from users show that after 3-5 removals, the gooses will perceive the area as unsafe and settle in nearby areas. In this way, the gooses can be herded to areas where they do not damage crops or recreational areas. This makes it possible to avoide crop damage and the goose can stay in areas where they avoid stress by being chased away. Several municipalities no longer allow hunting and recommend laser instead.
The Norwegian Institute for Nature Research (NINA) have in cooperation with municipalities and farmers conducted a 2 year test with our portable laser. Feedback from farmers was 100% efficiency of the laser but they would like an automatic laser to get 24/7 protection.
Tests we have carried out in aquaculture facilities and waste dumps shows that our new 1000mW@1meter laser also gets rid of seagulls, with the old laser of 500mW@diode seagulls responded poorly, this especially applies in aquaculture facilities and waste facilities where there is food in the picture.
OTHER BIRD SPECIES
Problem birds such as starlings and crows are easily kept away from breeding facilities with BIRDLASER STANDARD 1000mW@1meter.
Birds that needs special attention is endangered species, these birds cannot be killed or disturbed during nesting season. Installation of laser needs to be done before or after nesting season. Below is a list of the most common endangered bird species.

Aquaculture and bird droppings
Birds such as seagulls, can pick up and disseminate pathogenic micro-organisms such as salmonellae and faecal coliforms. The increase in bacterial concentration in reservoirs has been correlated with the number of roosting gulls. Some bacterial species isolated from bird faeces have been implicated in severe outbreaks of septicaemia and enteritis in salmon. In aquaculture this can be a huge loss and knowing that the fish is feeding on bird faeces is not a dinner conversation subject.
Geese, beaches and risk of infection
The population of geese has increased sharply in recent decades. The increased population creates challenges related to fouling with goose droppings on swimming beaches and green areas.
Bathing places by both fresh and salt water are often favorable areas for geese, especially when they are molting, i.e. when they change parts of their plumage and cannot fly (in the months of June-July).
Open-air areas such as bathing areas are often sown or covered with natural grass, and thus an attractive grazing area for the geese. Few predators such as foxes and mink, as well as people feeding birds on the beaches, give Canadian geese and other geese good conditions.
Feed loss in diary farms due to birds
In average a feed loss resulting in 4,4% decrease in revenue is reported from diary farms in Washington State, this is only feed related loss and health related loss is not calculated in but will probably be higher thant the feed loss. In average we estimate a 10% decrease in revenue due to bird related issues in diary farming. In addition comes property and machinery damage due to bird droppings.
Goose droppings may contain Campylobacter
Large amounts of goose droppings are primarily perceived as unhygienic. A clear connection between faeces and infection to humans has not been demonstrated, but geese are carriers of bacteria that can be contagious to humans. It is therefore recommended to be careful when dealing with faeces in the birds.
A goose produces faeces approximately every five minutes, and in the course of a day it can produce as much as 600-700 grams. Certain places can thus be exposed to significant amounts of faeces.
In 2010, Bærum municipality examined faeces and intestinal contents from Canada geese to look at the presence of microbiological agents (viruses and bacteria). Campylobacter Jejuni was detected in 70 per cent of the animals (Haaverstad 2012).
Campylobacter is a bacterium that can cause severe diarrhea in humans. (Institute of Public Health 2018). Case-control studies show that the most common cause of campylobacteriosis in our country is the use of non-disinfected drinking water, at home, in the cabin or in nature. Infection through the consumption or preparation of poultry products, and during barbecue meals, have also been identified as significant risk factors (MacDonald et al 2015).
