In the sixties, a lot of international studbooks were started and this was a field I was very much interested in. And so I checked in which species is Zurich still strong. And we, at that time, usually kept two breeding groups of vicunas and have had the most births worldwide in vicunas. So I suggested to start since the studbook and it was officially accepted. And I’m probably the longest acting studbook keeper, since I’m still keeping the international vicuna studbook.
