The Working Group on Raptors in the northern part of The Netherlands has been monitoring the numbers, breeding success and persecution of raptors since 1982. The activities have become country-wide by 1994. The present survey is a summary of results obtained during fieldwork in 1994. Most study plots are still situated in the northern part of The Netherlands, especially in the provinces of Groningen, Friesland, Drenthe, Overijssel, eastern Gelderland and IJsselmeerpolders (Fig. 1). Several of these study areas will be treated separately in the present issue of De Takkeling. Data on ten raptor species were obtained (Table 1), covering 5-72% of the respective Dutch breeding bird populations. Recommendations are made which species and areas deserve special attention in the future, and which species are already being covered sufficiently (Table 2).
