In the province of Noord-Brabant (5106 km2), cases of raptor persecution were collected and analysed. Many species of birds and prey and owls fell victim to persecution of one sort or another (Table 1 and 2). Poisoning (often with aldicarb or carbofuran) was apparently the most popular method, but many instances of nest disturbance were also registered. For example, in the Forestry De Kempen (1500 ha of woodland) not a single Goshawk fledged. Mass poisoning was recorded in the Staarljesche Peel (13 raptors).
