Firstly, I haven't seen the Orang exhibit at Chester, but it sounds far better purely for the natural vegetation in the enclosures and for the cover it provides. I expect most users of this site will not see a zoo exhibit with the same eyes a child or occasional zoo-goer might, and with Dudley and Blackpool Zoos sorely lacking in their presentation these animals and the threats facing them, the exhibit at Chester may be inspiring. European zoos are only recently starting to move away from a moated lawn with a dead trees or climbing platforms for Orang Utans. This is why it is so puzzling that London has gone for essentially this same kind of display for its Gorillas. The point made about the abundance of electric wire is very true - I need to read more but there are some studies on enclosure use for various species where 'hot' wire is used to enclose them, the plants in Gorilla kingdom may look fantastic in a few years, but I suspect the animals will not go near them with all the electric fencing. I guess thats the point, but it's a shame when a progressive minority of zoos allow access to live trees (for example Nuremberg).
Somebody also mentioned the Colobus tunnel as something they disliked. While I have no opinion on the aethetics of the tunnel, I wondered if anybody knows of zoos where Gorillas are successfully mixed with colobus, or guenons? Bristol has a tunnel linking the De Brazza monkey enclosure with the Gorilla Island, but as yet I don't think they have attempted to mix them, with both groups having very young animals (correct me if you know otherwise). A few years ago, I believe Port Lympne attempted to mix colobus, and later Diana monkeys, with their Bachelor Gorillas, several monkeys were killed by Gorillas, so the attempts to mix them were halted (there is still a monkey cage with connecting tunnel next to 'palace of the apes, ususally remaining empty). Howletts did the same around the same time, using Spot-nosed guenons and Samango monkeys, this was successful with the spot-nosed monkeys, although they never bred and only 1.1 remain, while the Samango were moved to Port Lympne. At London and Bristol, you might expect that on introduction, any aggression from the Gorillas would cause the monkeys to take to the highest tree, rather than to run, on the ground, to the one exit point available to them on the island. Neither enclosure has a great deal of climbing apparatus, and certainly none that would be out of reach to a Gorilla chasing a colobus monkey.
Does anyone know how the staff at London are planning to go ahead with the introduction of the colobus?
