You cannot say how the keeper position is in Europe. You have to separate from country to country. In Switzerland, we were only three recognized zoos, at that time. And so the market for zookeepers was very, very small. And so we didn’t have an official training but we accepted only people with profession say successfully finished. So if they didn’t succeed in Zurich Zoo, they would never have received a position in Basel Zoo or Bern Zoo because we so closely worked together. And so the keeper could go back to his original profession. And, therefore, new keepers just had to learn from the resident keepers.
