The use of poison to kill predatory animals occurs in almost every country in the world. In the past, "natural" poisons, such as wolfsbane, were used. Today, modern pesticides - above all insecticides - are more common. Victims are almost always birds of prey.
The perpetrators usually use dead wild animals, slaughter waste or chicken eggs to bait and poison birds. Since baits are also used legally for hunting, e.g. to attract foxes, it is not always easy to distinguish them from illegal poison baits. It only becomes clear that poison is involved when dead birds are found next to the baited remains. There is also a method which involved coating live pigeons with poison and letting them fly. This way, falcons and hawks, which rarely eat carrion, are more easily killed.
