Grandson of ex Bristol Zoo pair 'Adam' x 'Anne' He came from La Santillana in Spain in order to be surrogate-raised with other Orangs. Only Sumatran at MW.
Unless they brought in a Sumatran partner(s) for him and started a Sumatran group? I would like to see another holder of Sumatrans in the UK, even if it was MonkeyWorld!
Nowadays because they work in conjunction with the EEP who send them youngsters from other Zoos for socialisation purposes, I think they could easily receive a Zoobred Sumatran youngster or two to keep more permanently if they wanted to. I doubt the 'rescue' part would be any obstacle and it wouldn't be the first time anyway- 'Gordon's father 'Bangi' was a surplus zoobred male from Chester.
