If the changed the site, perhaps more dutch speaking people will come.
It is true, some people in Flanders (the Dutch speaking part of Belgium) prefer the Zoo of Antwerp, or Planckendael in Mechelen just because there aren't many Dutchspeaking people in the Walloon part (the French speaking part of Belgium). It is not so easy to move in a part of a country when you don"t speak a language they understand. English is not standard known by the people in Walloon. And French is not always known with the Flemish people. As a flemish person, i had barely some French lessons in my education for example... English i did have...
But that the "big problem" of the nation Belgium nowadays, and that is mayby a big offtopic discussion, but it affects Paradisio for sure. There are more people that speak the both languages in the Flemisch Zoo's, then in the Walloon Zoo's.
For example, Paradisio even needs to borrow Dutch speaking guides from the Antwerp Zoo. It is stupid, but it is a big fact...
But ok, back to the cute little birds?
