Crow clap
The crows swatter is a simple and cost- bang device for acoustic deterrence of rooks . This type of acoustic deterrent for birds is primarily used in cities.
functionality
The crow's swatter consists of two long flat boards that are connected by a pull rope. It is hung in a treetop with crow's nests in such a way that the pull rope hangs above the ground within reach. By pulling the rope, the two boards are knocked together, causing a loud clap in the treetop. The crows are startled by the loud noise and leave their places in the tree for a more or less long time. Ideally, the crows look for a quieter spot after a while.
Use using the example of the city of Jever
In the Frisian town of Jever ( Lower Saxony ), this device is used against crows in several trees. Passers-by, tourists and especially children use this self-service device with enthusiasm. The smart approach to driving away the crows, which were perceived as a nuisance, did not quite bring the desired success, but developed into a secret tourist attraction.
In 2008 a crow population with 457 nests was counted in Jever . To the chagrin of the majority of the citizens of Jeveran, the animals are in the inner city area within the grafts of the old town. In addition to the noise of the birds , the falling excrement of the many animals also disturbs . This circumstance led to resentment among market deliverers and market visitors at the weekly market held twice a week on the church square. Since the crows are protected by law in Lower Saxony, some methods of eviction were tried, but they did not bring the desired success. After the topic reached the city council , the public order office, on the initiative of the former city director Ingo Hashagen, put a crow clap in one of the trees on the market square. This enabled the problem of falling debris to be contained by clapping during market time. As a result, more crow claps were installed in other places in Jever.
