I have visited zoos with groups and with one other person and have had variable experiences. I can find groups a bit difficult. I try and be democratic, but I find that there is a tendency for visitors to choose the ABC animals, rather than the animals that are unique to that zoo. I have read about escorted parties being taken to Beijing Zoo. "Here are the pandas. You've seen the pandas. Now we leave the zoo." Similarly, a former zoo volunteer went with a group to Taronga Zoo. They were marched to the kangaroo enclosure, saw the kangaroos and left the zoo. When I went to Taronga Zoo, I wanted to the see the platypus, but I think I spent more time trying to photograph a male lyre bird.
Most of my zoo viits have been with a member of CAPS. I'm afraid that my friend doesn't agree with zoos in general, but she quite liked Cologne and Prague zoos. She noted the Owston's palm civet at Frankfurt Zoo and said, "You haven't seen that before." I hadn't, but I don't know how she knew this. She didn't like Stuttgart and had mixed feeling about Plzen. Neither of us were impressed by the small enclosure for Barbary lions in the Small Mammal House (I must admit that I've never thought of a lion as being a small mammal). She also wasn't impressed that the dusky pademelon we saw can only be seen at Plzen (according to ISIS). I have been to zos with other people who are not zoo enthusiasts and I find it can be useful to be told about welfare problems that I wouldn't have noticed decades ago. I agreed with one friend that a Persian leopard was showing stereotyped behaviour and seemed to be in distress. I think it is easier to visit zoos with like-minded people, but it is better to have your views challenged occasionally and see different aspects to zoos and their animals.
