Across Europe, birds suffer from a wide range of persecution: illegal poisoning shooting, trapping, and the theft of chicks for the bird trade are common practices. Recently, five European countries were confronted with cases of illegal killing. The common, even if illegal, practice of using poison baits to eradicate carnivores and rodents causes huge damage to wildlife as well as to livestock and crops. In some cases it can explain the decline of specific bird populations in Europe. Moreover, the poisons used are usually unnecessarily strong and often illegal.
