Longtime zoo professional Alan Toyne has a new book describing his many years working with lowland gorillas at Bristol zoo, including two experiences hand-rearing baby gorillas. Gorillas in Our Midst: A zookeeper's tale of hand-rearing baby gorillas published by Summersdale centers on the lives of extraordinary characters like a female gorilla named Kera, a lone hand-reared female that never knew how to be an adult gorilla herself. When Kera had to deliver by C-section, she failed to bond with her infant Afia. That's when Alan and his fellow keepers stepped in and provided around the clock care for her until such time as another female stepped up to raise Afia as her own. Years later, when another infant, Hasani, needed a surrogate, Alan and the team made the bold decision to train Kera for the job. Could the once ostracized gorilla that rejected her first infant learn to nurture another?
