Bird control
The Bird control is an expression of the pest and describes all the methods to scare unwanted birds or to prevent them from landing and nesting.
Defensive measures
Depending on the situation, different defensive measures or combination of different defensive measures are applied. Special features of the protected buildings and facilities must be involved in the selection of defensive measures. A basic distinction is made between the following measures:
Physical measures
- Networks
- Grid
- Bird control spikes ( pigeon spikes)
- Tension wire systems
- Electric defense plants
- Bird dummies, so deceptively similar replica of birds, mostly in the form of birds of prey
- Scarecrows
- Reflective objects (mirrors, CD / DVD ' s hung with reflection on cord / cord which act by disturbing air movement )
Acoustic measures
Acoustic Bird control measures are often used on large open spaces, such as in agriculture, viticulture and in the bird strike defense at airports. The high -pitched tone of ultrasonic devices to scare the birds, but can be heard by people under certain circumstances. Acoustic measures such as bang devices, sonic and ultrasonic devices and bird cry devices are controversial and can lead to disputes with local residents, for example, with automatic constant noise. Also, is not yet scientifically proven, whether and to what extent the acoustic measures have a mitigating effect.

Reasons for Bird Control
- Avoid bird strikes at airports.
- Birds can be carriers of pests, parasites and diseases that can be transmitted to humans. In particular, infectious diseases, among others, Ornithosis ( psittacosis ) can be transmitted to humans. Parasites from the plumage of the doves, and the present in pigeon droppings pathogens can cause disease in humans, especially when food is contaminated, for example, in markets and in the open-air restaurant by pigeons.
- Parasites of the pigeons occasionally go over to the people when the city pigeons nest in attics, etc.. This is particularly often by pigeon ticks ( Argas reflexus and other Argas species) reported less frequently by other parasites such as pigeons fleas ( Ceratopsyllus columbae ), Red Mite ( Dermanyssus gallinae ), Nordic Mite ( Ornithonyssus sylviarum ) and bed bug ( Cimex lectularius ).
- Each city pigeon produces ten to twelve kilograms feces per year; this is highly corrosive. When doves occur at or around historic fabric reinforced, it will be seriously damaged. Clogged by nesting material and droppings gutters lead to the ingress of moisture and consequential damages, such as the attack by dry rot.
- Dust from droppings can trigger allergies and Federteilchen: The " pigeon fanciers lung" is a based on an allergic alveolitis pneumonia.
- Bird carcasses attract pests such as skin beetles and mites.
- Birds can cause significant crop damage, for example by pecking of grapes in vineyards. Especially in the vicinity of overhead power lines and other preferred seating positions winegrower fear being eaten by birds.
Criticism
Critics of the bird and pigeon control argue that the damage caused by birds to be lower than is shown. The disease risks are not as high, as represented by proponents of defense. In addition, there is criticism that the measures to ward off would often ignore the health of the animals.
Legal
The Hessian Administrative Court feral pigeons, among other things classified as pests, " when they occur in practice typical larger populations ." As such, they must be fought and killed under certain conditions.
"Mecklenburg- Vorpommern has classified the common pigeon as animal pests (health pests) in § 1 of the State Regulation on the control of health pests on 26 June 1992 ( GVOBl. M.-V. 1992 p 37); as Saxony -Anhalt in § 1 of the Regulation on the establishment and fight an infestation by animal pests of 14 February 1996 ( LSA 1996 GVBl. p. 112). "
