Sri Lanka, April 20 -- April 20, (Guinness World Records) - Bella, the world's oldest living orangutan in captivity, celebrated her 63rd birthday this week.

Estimated to have been born in 1961, Bella the Sumatran orangutan (Pongo abelii) was collected from the wild in 1964 and has lived at Hagenbeck Zoo in Hamburg, Germany, ever since.

Zoo staff said that Bella "is in the best condition".

She was given a birthday cake made of soft-boiled rice and various fruits, which she shared with Berani, one of her adopted children.

The typical lifespan of a wild orangutan is 35-40 years, increasing to around 50 years in captivity.

Bella became the oldest living orangutan in 2021, following the death of Inji, a female Sumatran orangutan at Oregon...
