Since 2002, raptor nests have been mapped and checked in the Noordoostpolder, central Netherlands. Starting with 7 successful nests in a small section of the polder in 2002, the size of the study area and the number of raptor nests visited increased to include the entire Noordoostpolder and 200-250 territories in 2016-17. Nests were initially checked with binoculars from the ground, few nesting trees were climbed. Later on, tent sticks were used to create a telescopic stick with mirror to check the nests’ contents. From 2010 onwards screw-threaded carbon sticks were used with a camera mounted on top. More recently, professional window washer’s cleaning poles are used with an HD-camera. On the same pole, a mini-camera is mounted next to the HD-camera to target the latter. The length of the telescopic pole amounts to 13.6 m (increasing to 15.5 m when height of raptorphile is included). A fitting is made in the lower pole, to add extra carbon poles (increasing total length to 27 m, sufficient to check almost all nests, provided that the pole can be stabilized with branches below the nest). Nests can now be checked in 5 minutes’ time, seriously reducing the disturbance at active nests. The films can also be used to identify prey remains.
