Think some of these imported ones were for 'redistribution' to other zoos, maybe making up fresh pairs with some of their own homebred ones. Twycross recently got a pair from them.
I think one reason L'Hoests may be successful is they are quite a bold species of Guenon, unlike e.g. Hamlyn's, so maybe less prone to stress in Zoos and therefore breed more freely.
You’re absolutely correct; I believe L'Hoest’s "guenon" is quite different to other guenon species. I remember reading a paper which suggested it is more closely related to Chlorocebus and Erythrocebys, which would certainly support the fact they apparently reproduce more freely in captivity.
I'm afraid the gradual decline of Guenons in captivity is completely down to mismanagement. These animals are routinely only housed in pairs, there’s an apparent lack of motivation to move individuals between collections to promote breeding and I believe all species will be lost without fresh imports and/or competent management.
Unfortunately I will have to disagree with you, Pertinax, when you say that Dianas are stable. I’m sorry to say they are also in decline.The studbook keeper was done nothing about the non-breeding mother son pair at Exmoor, the groups lacking males or the non-breeding pairs throughout Europe. These animals should be amalgamated into larger groups in fewer institutions. If the current studbook keeper is no longer interested in their role I would happily take on their duties.
