When zoo keepers entered the Gorilla House at the Netherlands' Burgers' Zoo on June 13, they were taken by surprise: N'Gayla, the 20-year-old female Gorilla, had delivered twin babies overnight!
It was known that the 20-year-old female gorilla was pregnant, but not that she was expecting two baby gorillas. A twin birth from gorillas is only occurs about once or twice every ten years in zoos. Gorillas usually get only one young at a time. Twin births are for them rarer than in humans. Mother and babies are doing well.
Mother N'Gayla literally has her hands full with her little ones :o).
