The Zoo announced the passing of White-handed Gibbon Holly today.
"We are saddened to announce the passing of Holly, a 50-year-old white handed gibbon.
Holly lived at the Toronto Zoo for the past 43 years, most of which was spent with her long-time mate, Lenny. Holly was a big personality in a tiny body. She was known for her loud voice and for always carrying around a stuffed toy, or, in recent years, a squeaker toy. Holly enjoyed crickets and mealworms which she would gather and place on her stuffed toy to eat. She always made her keepers work to earn and keep her trust, even those she knew the best.
The Zoo opened almost half a century ago, and few animals from that time are still alive today. Holly was one of these senior citizens, along with Charles, Puppe, and Jonah. These special animals have outlived their wild counterparts by decades. The life expectancy for white-handed gibbons is about 30 years in the wild and in human care, they often live to be 40+. At 50, Holly was one of the oldest gibbons in North America.
This past Sunday, Wildlife Care staff noticed Holly had an injured thumb, and she was sent for x-rays to determine the extent of the injury. Unexpectedly, the x-rays showed she also had arm fractures – despite the keen eye of her keepers, she had masked these injuries from them. There was no conflict with Hoot or any other incident observed that might have led to these injuries, so we are unable to confirm what caused them. It is possible that, as a very elderly gibbon, Holly had a condition such as low bone density that could have played a role in her bones being brittle. Given her advanced age, complicated condition, and challenging recovery, our team made the difficult decision to humanely euthanize her.
We are so grateful that Holly was able to spend the last few months of her life bonding with Hoot; her last few weeks were spent hugging and grooming her new friend and we find comfort in knowing she was not alone. Keepers will closely monitor Hoot as he adjusts and ensure that he has lots of attention and enrichment to keep him occupied.
Holly will be deeply missed and the Indo-Malaya Pavilion will not be the same without Holly's lively presence and big voice. Read more at the link in our bio."
