To answer your last question: For the same reason the zoo berlin and other"world-famous"zoos promote elephants, tigers, polar bears, seals, penguins, giraffes...the people want to see them-and the people bring in the money, not the Kiwi,Aye-Aye or he Gerenuk...money what is needed to show also other species. See what is happening to a zoo who is not keeping these species...best example is the RSCC....
By the way-I think, even the smallest zoo has room enough to keep merkats and I never heard before that any zoos has stopped keeping another speices to get the space for a merkat exhibit...The first thing I would do If would take over a zoo without merkats would be buidling a merkat exhibit...
Hello Bib Fortuna
I haven't said that Berlin Zoo should get rid of its elephants, tigers, polar bears, seals, penguins and giraffes, although I don't think that the same species should be kept at the Zoo and Tierpark, but that is a different subject.
What I was commenting on is the choice of animals to promote Berlin Zoo. I suspect that some visitors would expect to see the usual subjects; there are still people expecting to see elephants, polar bears, giant pandas and koalas at London Zoo. I also suspect that many children know about a greater range of animals than their parents do. Some recent books and TV programmes include animals that would have been ignored 20-30 years ago and some popular films have included clown fish, aye-ayes, fossas, warthogs and Spix's macaws. I wonder how many of the parents are really interested in animals and I have heard some children coming out with factual information that contradicts the misinformation of their parents.
A zoo's website is a means to attract people to the zoo and I feel that Berlin Zoo should have used more imagination when it chose its species. I would have thought that a website could include animals such as kiwis (a flightless bird with tiny wings and nostrils at the end of its beak), aye-ayes (an animal of many myths that was mistaken to be a rodent, but with a range of feeding adaptations) and gerenuks (an antelope with a long neck and legs that can stand on its hind legs to reach leaves). A photograph and some basic facts could attract visitors to see animals that are not in their local zoo.
