Pieter guided 3 of us on a weekend of winter birding in Holland. Even in difficult weather conditions we managed to see 90+ species in 2 days including 8 geese species which were our target birds. He is an excellent guide who knows the sites and birds well. Perhaps as importantly he is also extremely good company which made the whole experience very enjoyable. We will be back, and with Pieter.
