Berlin Zoo’s oldest gorilla Fatou turns 69 with vegetable feast

Berlin Zoo marked Fatou’s 69th birthday with a vegetable feast of cherry tomatoes, beets, leeks and lettuce, skipping cake because sugar is not healthy for the aging gorilla. The celebration on Monday, April 13, placed a spotlight on an animal whose age has become a rare measure of both zoo medicine and the limits of captivity.

Fatou is a western lowland gorilla, and her exact birth date is unknown, so April 13 serves as her official birthday. Zoo Berlin and Guinness World Records say she has lived at the zoo since May 1959, when she arrived in what was then West Berlin at about 2 years old. Guinness estimates she was born in the wild around 1957, which makes her longevity far beyond the norm for her species.

That is what makes Fatou such a case study for modern geriatric animal care. Guinness says western lowland gorillas typically live 40 to 50 years in captivity, while gorillas in the wild usually live about 35 to 40 years. Fatou has already outlived both ranges by decades. She has lost her teeth, and keepers say she also suffers from arthritis and hearing loss, conditions that require a softer, carefully managed diet and close monitoring from veterinary staff.

Zoo Berlin has kept Fatou in her own enclosure, where she lives separately from the other gorillas but can still socialize with neighboring animals when she wants to. The adjoining gorilla area has included the silverback Sango and females Mpenzi, Bibi, Djambala and Tilla. Christian Aust, the zoo’s primate supervisor, has described her as friendly with keepers even if she is stubborn, a temperament that appears to match the independent life she has settled into in old age.

Her story also carries a larger conservation message. Berlin Zoo director Andreas Knieriem has called Fatou an ambassador for her endangered relatives and a reminder of why biodiversity and intact habitats matter. That framing is tied to the species’ real crisis: the western lowland gorilla is listed as Critically Endangered by the International Union for Conservation of Nature, which cites poaching, disease and habitat loss, including deforestation and mining. The World Wildlife Fund says numbers have fallen by more than 60% in the last 20 to 25 years.

Fatou’s arrival carries a legend of its own. Guinness says she was found in western Africa in 1959, taken to France by a sailor who allegedly traded for her in Marseille to cover a bar tab, then sold to Berlin Zoo by a French animal trader. However she reached Germany, she has become a city fixture, a living record-holder and a reminder that the rarest birthdays at a zoo can also reveal how institutions now care for animals that have outlived the systems built around them.
