I suppose this is a bit of a risk with these shows, especially with rather slower bird species. I once saw a turkey vulture try to fly inside a small mammal house, but the outcome there wouldn't have been bad for the bird. It would seem unusual to have a lynx exhibit that isn't meshed over, it must be a good size.
Because in 2015 GaiaZoo has its 10th anniversary, they have some big plans :
New South America tropical Hall
Giant anteaters
Anaconda
Pygmy marmoset
and a lot of other new species !
Strange they call it in the title of the article "Limburg Zoo" because the now closed very bad zoo at Genk Zwartberg in Belgium had almost the same name Limburgse Zoo.
Gaia Zoo is however a very good zoo and is in the Dutch province Limburg.
The terrrible Belgium Zoo was however also in the province Limburg but in the Belgium province Limburg.
