I can understand different people/organisations having different views about the taxidermy of our nearest relations and why this can therefore be an emotive issue. A number of zoos have statues made of their most famous Gorilla but the dead animal has also become a museum display too e.g. Guy, Alfred (Bristol Zoo), (probably) Jambo at Jersey, also Bushman and Phil (Chicago and St Louis Zoos, USA), possibly 'Bobby' at Berlin also. Edinburgh have a statue of their early Sumatran Orangutan family but the mounted animals are also in the Edinburgh museum.
One person I am sure would never have considered such an outcome for his Apes was the late John Aspinall- I believe all the Gorillas that have died at his two collections are buried there as they were very much regarded as part of his extended family. There is also a statue of one of their earlier males 'Gugis' near the Gorilla enclosures at Howletts.
I think if I was emotionally involved with any of the animals e.g. as keeper or owner then I probably wouldn't want that to happen to them either. I must admit to have a slightly uneasy feeling about the idea of a stuffed 'Jambo'.
