Schad birds

Certain bird species such as throttle (Blackbird), pheasant, partridge, Sparrow and star have it at maturity from August or vintage apart from the sweet grapes and can cause a considerable reduction in yield. Bird plagues in the vineyards have been described since ancient times and are still a problem worldwide. In spring and summer they can be used as insectivores and thus beneficials but be very welcome. In extreme cases, very large flocks of up to 10,000 birds and more can occur, this is especially true for the star to. If a flock of birds settles on a vineyard, it is "harvested" in a short time. A negative side effect is the penetration of microorganisms such as damaged or picked berries bacteria and mushrooms and thus the appearance of bunch rot favored.

Various measures are used to try to prevent this or to limit the damage. The earlier use of ovicidal (Pesticides) is severely restricted or even banned at all. As a substitute, “scare agents” (repulsive substances, repellents) are used, which are perceived via the sense of smell, but do not kill. This also includes physical methods. A relatively complex form is covering the vineyards with nets. Here it must be ensured that the nets are visible to the birds so that they do not fly against them and injure themselves.

But often it is optical devices like scarecrows, acoustic wind powered, noise causing devices like the Klapotetz, Tapes with birds screaming or gunshots, airplanes or personal surveillance by one Weingarten guardian, As a result, the birds should be distributed to all vineyards in a larger area as far as possible and the damage to all winegrowers should be kept to a minimum. This is part of the biological respectively. Integrated crop protection used.
