Are Bird Scarers Legal

Manually operated laser burners and automated laser alert robots for birds that automatically move the laser to birds are available on the market. Fireworks can also be used as bird scares, and some jurisdictions issue special licenses for agricultural fireworks. [10] This practice has been criticized as a loophole for the sale of fireworks to consumers. [11] Again, strong blows can irritate people living on nearby properties. Relevant legal controls The Firearms Act 1968 stipulates that a firearms certificate must be issued when bird alert cartridges are used. The Environmental Protection Act 1990 contains powers to deal with harassment by hearing scars on birds. These have been successfully used to prevent farmers from using such scars. These combine several deterrents, such as the use of a pop-up scarecrow in combination with a gas gun, which in turn activates a bird`s distress call. These combined scarers are often managed by computers and synchronized to an area via radio links. This synchronization becomes more efficient when there is some kind of detection system like bird detection radar.

In 2013, Dr. John Swaddle and Dr. Mark Hinders of the College of William and Mary developed a new method to deter birds with benign sounds projected by conventional and judicial (parametric) speakers. [8] The initial objectives of the technology were to move problematic birds from aerodromes to reduce the risk of bird collisions, minimize agricultural losses due to foraging harmful to birds, move troublesome birds that incur significant chronic repair and cleaning costs, and reduce bird mortality by flying in artificial structures. Sounds, called „Sonic Net,” don`t need to be loud and are a combination of waveforms – collectively called „colored noise” – that form an unconstructive and constructive disturbance of how birds talk to each other. They are also used at aerodromes to prevent birds from accumulating near runways and pose a potential danger to aircraft. Gun laws prevent magpies from being shot near public roads and homes. We are not against the legal and site-specific control of magpies, nor against the legal use of Larsen or other cage traps, as long as the general license conditions are strictly adhered to. Lethal control (killing) of pigeons, gulls and other wild birds in the United Kingdom is enacted by the Department for the Environment, Food and Rural Affairs (DEFRA) through the Wildlife and Countryside Act 1981 (Chapter 69), which effectively signals that it is illegal to kill or injure wild birds, including pigeons. Ultrasonic devices are static deterrents emitting sound emissions that theoretically hinder birds to move them away from closed or semi-enclosed areas.

Ultrasonic scarers are not harmful to birds, but there is debate about the ability of birds to hear these frequencies at sufficiently loud decibels. Birds are thought to have similar hearing to humans, with studies showing that birds do not hear ultrasound,[7] meaning that ultrasound scars often have little or no effect on bird deterrence. [3] Studies conducted at Wageningen University[2] show the potential of laser technology to prevent the spread of avian influenza. When the laser was used on a poultry farm, a reduction rate of 99.7% was recorded for wild birds. Sonic Bird repellents are not effective; Birds quickly get used to it. The system, which usually consists of a central unit and several speakers, sends emergency calls digitally recorded by birds and, in some cases, calls from predators of the target species. Some transmitters randomize height, size, time interval, sound sequence, and other factors to prevent birds from getting used to it. Many of the sounds produced are considered boring for people.

Fireworks have been shown to be effective in spreading birds in airports, landfills, agricultural crops and aquaculture facilities.

At UK airports, crackers fired by a modified gun are the most common way to disperse birds, as they allow the bird controller to have some directional control over birds in flight so they can be moved away from the runways. The use of predators as a natural deterrent to birds has become a recommended form of bird infestation control.
