Bulu- I believe she may now be the only(past)inhabitant of London's old Monkey House building who is still alive. However there were a number of other Orangutans living in there(imported as babies) and a couple were later exported again so I'm not 100% sure. I really hope 'Bulu' can make it to fifty (at least).
It's a shame they don't make more of her special status though. As her unofficial advocate, I sometimes enlighten visitors about her age and life story and they are usually amazed.
has anyone got pics of the orangutans because i always get mixed up ! and happy bday bulu lets make 50 shall we !
