Thanks for all the photos of these incredibly educational signs. I think I found a mistake on one though. On the camels one it has wild camels as a species that live in Australia but the diagram next to the map shows a bactrian camel, not a dromedary.
My pleasure - I've also taken some photos of similar boards in Berlin Zoo. Although those photos are generally even worse than these, it's interesting to compare how both zoos illustrate the same concepts. I'll upload them soon.
