@Mr Gharial More weird than cool in my opinion. Mixes with turtles and snakes I've definitely seen before elsewhere, and there are other exhibits at Pairi Daiza with a turtle/snake combination, but the mix with the small birds is odd.
The sizable snake (viewable at the back next to the plants and logs to the right of the door) is probably too large to bother with the small finches and I guess the turtles might not prey on birds either. But I still find it an odd and risky mix.
