The problem of aggressive, loud and annoying gulls has been on the political radar of Leiden, the Netherlands since 1988. That was when the fox population of the nearby sand dune area Meijendel was displaced. Because the gulls built their nests in the Meijendel sand, they were easy prey for the foxes. Since there are no foxes in the area anymore, the population of gulls in the dunes has increased so much that individuals must seek shelter elsewhere. So the gulls came to Leiden.
The gulls cause the most nuisance during their breeding season, when they make the most noise. They shriek the loudest at possible predators or behaviors they regard as potentially dangerous. The gulls can become aggressive if they feel threatened enough. The breeding season begins in mid-April.
In April 2005 the local government issued a statement with recommendations on how to reduce the nuisance caused by the gulls. The most significant recommendation was to reduce the amount of garbage on the city streets, which the gulls forage for food. “A clean city insures less annoyance.”
This year another proposal has been given. Leiden council member Sabine Verschoor from the political party D66 is promoting the shaking of gull eggs in order to limit the population and therefore the nuisance caused by the cacophonous birds. Thus far, shaking has been prohibited as the gull is a protected bird. Verschoor hopes that a pilot phase allowing shaking will bring clarity to the situation: “Now you cannot do anything, while half of Leiden suffers from the nuisance.”
D66 Leiden has proposed another solution for dispersing the annoying birds: placing wires on rooftops which will make them undesirable places for the birds to roost.
According to council candidate Aad van der Luit, a solution such as this will only work if entire streets will participate in the program. If the birds are able to find an alternative rooftop on which to land nearby, the wire program will fail.
