Extremely sad, but not unexpected, news. The fact that Charles lived to such an absolutely extraordinary age, and left behind such an impressive legacy, does help soften the blow somewhat, but this is still a rough one all the same.
However with his passing, this also ushers in an age that will undoubtedly be full of prosperity and opportunity for the Toronto zoo gorilla troop. It is extremely, extremely likely that the zoo will receive the silverback Jawara from Granby in the very near future. Given the fact that both zoos are within Canada, relatively close to each other, and there are currently no gorillas that are within the age range where it’s risky to introduce a Silverback at Toronto, I would say the chances are very high that he could be arriving within the next month at most. He’s an extremely genetically valuable silver back, and completely unrelated to any of the gorillas at Toronto. This will also enable the even more genetically valuable Johari to FINALLY start breeding, which is not only nice from a genetic standpoint of things, but will also be amazing for Johari socially. She’s definitely at the bottom of the pecking order in the zoos group currently, and being able to finally have offspring will offer her support both in terms of having support from having Ngozi and Nneka going after her, and just plain social interaction in a way that only mothers and their offspring have. And of course having a young, healthy silverback in his prime will also likely help with that tremendously as well in general.
In truth, there was a somewhat similar situation at the Calgary zoo with their silverback Kakinga. He was a wonderful silverback, but old, and there was more social strife than necessary towards the end of his life leading over the troop. With the arrival of a new, young silverback, not only was there an increase in breeding and offspring, but social tension got much reduced between the girls, and saw an increase in affiliative behaviours as well as a massive decrease in hair plucking and other undesirable behaviours from the females thanks to the more effective social management from the younger and more involved silverback.
