Rajang was the first orangutan to be born and successfully reared at Chester, back in 1968. Chester originally had a 'group' of five or possibly more orangs, including two males 'Jimmy' and 'Paul' who outlived all the females by many years. Rajang's mother 'Josephine' wasn't interested in him so he was raised by the-then curator Bill Timmis and his wife. Later he was kept with a young Chimpanzee for company, before the zoo aquired more young orangutans. In those days little importance was given to the subspecies(or species) of Orangutans but later it was realised that both males(his father was believed to be 'Jimmy') were Sumatran, while the mother was Bornean, making him a 'hybrid'.(His blood may have been karyotyped in order to prove this) 'Rajang' was the only crossbred orangutan at the zoo and so wasn't of any value for the breeding programme. In 1980(or thereabouts) he went to Colchester Zoo, where he still lives today. He has had two partners there, first a hybrid 'Annie'(from USA) and since her death, a Sumatran female 'Djambe (came from Twycross). 'Rajang' was vasectomised to prevent him producing any further hybrid offspring. He is now the only crossbred Orangutan in the UK, but is also the oldest male too. New accomodation for Colchester's orangutans is due to open in 2008.
