We felt like kids in a zoo...
...but we were in a zoo.
Echidna spikes
This eland was standing in a pool of blood, which was dripping down from its horn. The vet told us that the horn was probably broken off in the fence, since the eland is normally a passive animal. The other animals in the herd were initially trying to chase it away because predators would be more likely to attack when there was an injured animal in the group. The horn eventually stopped bleeding, so no treatment was needed.
Siamang monkeys have a very impressive song to mark their territory.
