The recent order of males at ZSL was Bobby (died)- Yeboah(died)- Kesho(replaced)- Kumbuka(present).
Kesho replaced Yeboah after his death. An entirely normal mother-raised male born in Dublin, it was amazingly bad luck when they discovered he had Klinefelter's Syndrome which causes infertility. About a year after they found that out, he was moved to a bachelor group to live with his two younger brothers from Dublin- whom he immediately recognised and started to play with as soon as he saw them again at Longleat Safari Park. Kesho was pretty much silverbacked but not quite fully developed on arrival at London. Because of his youth, he was still extremely playful, particularly with the youngest female Mjuku-after attacking and killing her baby(Tiny) when they were first put together.
I saw Kumbuka today and he is a large and impressive male. There was a sign saying he was born in 1997. I've heard of Klinefelter's Syndrome in humans, I had no idea it was present in gorillas. Did Kesho look any different physically? It's amazing how long gorillas and chimps can go without seeing a relative and still remeber them. I read a story of a chimpanzee called Sally at the Hamilton Zoo who recognised the lady who handraised her, after 40 years of not seeing her. Maybe after Frala has finished her stint as a breeding gorilla at Taronga (if they breed her with Kibali), she could be sent to Prague Zoo as support for her daughter Shinda, who doesn't seem to be able to breed. This would be very costly however and perhaps not advisable as by that time Frala would be in her fourties.
