Jock is probably no longer an option.
Why Jock did never breed at London Regent's Park is not clear. Was it the stainless steel caged exhibit that did it ....??? Was it the fact that both females where not exactly the youngest birds on offer and had been childless for so long???
But then, why on earth did original male Kumba bred successfully to the then young females Zaire and Salome in the first place???
If I am correct male Kumba went on to become a very successful silverback at Chessington (if though their exhibit is not exactly state-of-the-art either ....!!! 
Or is it the smog and unhealthy air that somehow interferes with joyful love summer feelings to flourish in London's gorillas? Lack of Britpop? Too many nights at the local pub? Well, questions, .. questions.
The story becomes more confusing the longer you try to let it sink in ... (to be honest it won't .. it stinks .. sorry to say). Now that they have a new grassed up paddock it is even more complex.
Apparently, Zaire will not mix with young Effie (who has been rummaged around Europe several times). I personally think that it is time Zaire was sent out to a proven breeder (I do dare suggest Port Lympne Here) and let her become mother for a second and third time (there is still time for that, but not with good old ... sleepy Bongo - did he not breed at Rome Zoo once? question for Pertinax - at London). Further suggestion: get rid of the silverback male (he is no use), bring in a young well-socialised blackback male and 2 more females (one experienced young adult + perhaps her daughter) and make a real gorilla troupe!
London Zoo's record with gorillas is just not up to scratch (Is it management associated, keeper routines or a combination of both?). Does our resident panel here have anything worthwhile to say on this?
