Here the zookeepers had some "zootalk" before feeding the crocodilians together with the visitors.
Also, in the middle of this photo, near the branches, you can spot some hanging fruit. At first, I thought they might have birds flying around, but we didn't see any. Later, I checked zootierliste and found out they also have Egyptian fruit bats (Rousettus aegyptiacus) at the park.
So, maybe that is what is free-ranging in there and eat fruit, even though there's no signs or information saying so in the hall.
