Say, Kevin. Since you're ZC's resident Belgian. Could you try to take some pictures of the outside of the Shoebill aviaries? According to the Pairi Daiza map they currently have three different holding areas (One next to the reptile boat, One near the pygmy hippos, One in the African village)
@Mr Gharial I have previously posted pictures of all three shoebill aviaries in the gallery here at ZooChat, which you can relatively easily find. I'm not sure they will be exactly what you want though.
