This is a beautiful and interesting species of Forest Guenon, only exhibited in a handful of Zoos worldwide. The only Zoos in the UK I know of currently where they can be seen are at Twycross and Edinburgh. Does Bongo or BongoRob know how many there are currently at each ? And are there any elsewhere in the Uk now? These 3 zoos also exhibited them for a while in the recent past; London - their last male was sent to Antwerp recently. Banham- had a breeding trio in late 1990's but not since. Marwell- had 1/3 -a male from Edinburgh plus three(?) females imported from USA. They weren't there long but does anyone know what happened to them?
