There is a certain animal show in many zoos which is very popular among visitors: walking penguins on the road. Its popularity is not surprising, animals outside their enclosures are always interesting, and the clumsy, somewhat human-like toddling of the penguins is very funny to behold. Furthermore there is no need to worry about them escaping by running or flying away… Training the animals for this task is not too difficult, since this group movement is based on their natural behaviour. Nonetheless, this attraction – like other animal shows – is also a subject of criticism, both by experts and some animal right activists. In my opinion this question depends on the methods and context, but I’m open to debate and comments, of course.
