@SivatheriumGuy Sousliks got released on zoo grounds in 2006. They are somewhere between zoo animals and reintroduced wild animals.
The last traditional wild colony in Prague city at airport Letnany (where ancestors of these zoo animals came from) has unfortunately dissappeared few year ago.
The colony at zoo has been released on hill behind giraffe exhibit. But they colonised west part of the giraffe outside pen and now the new gorilla exhibit. They even sometime spend time inside the gorilla house. So that is approximate place where to look for them around.
It´s hard to tell probability to see them. They dont like rain and cold. And adults start hibernate already in August (younglings can be seen till September).
