Thanks for that, are the 3 females with the retired male also retired/too old to breed? If not, will they be integrated with the breeding group?
'Kumba's group consists of himself and Baffia, the female he was originally imported with circa 1970, who has never bred with him and will never breed now. The two others with them are the two youngest offspring of Kumba (Kuni is male, Kumili is female, both born in 2004 to Asili and Shani respectively)) who were placed in this group for safety as they were still quite small when new male Damisi was added to the main group. I presume the young female Kumili, now 8 years old, is being contracepted to prevent breeding with her old father.
Presumably, when the old male Kumba dies, the others will be added to the main group, or maybe the two younger ones will be at some time before that.
Chessington currently have three females(Shani(22) and her two daughters, Shangha(11) and Kumili(8)) now all of breeding age but seemingly(afaik) still being prevented from breeding, whereas it was announced this time last year that Asili ((21) she is also the mother of London's Mjuku) was being allowed to breed again to even up the family-line balance within the group. I do not know if she has become pregnant yet, but females that have been on contraception sometimes have problems with fertility afterward.
Regarding the Housing- originally it was planned to build a large new open Gorilla enclosure in the new African section but for some reason this was scotched (cost?) and an extra extension cage was built instead, next to the existing one, to give the smaller 2nd group fulltime access outside.
I don't know if plans for a completely new enclosure will be resurrected in future, perhaps unlikely. In the meantime, the potential of Chessington's group remains underused, with the apparent restrictions on the group's expansion.
