There are 6 river islands in Liberia, which are home to 65 chimpanzees.
These primates are the survivors of 400 chimpanzees who were used for medical research, funded by the US.
They're now being looked after by Richard Ssuna, a vet who works for the Humane Society International.
In the 1970s, the NYBC provided money for medical research for diseases like hepatitis B.
These chimpanzees experienced many medical experiments
The chimps also had to live through Liberia's 14 year war.
They almost died from a lack of food.
Research staff had to use their own money to feed the animals.
In 2015, the NYBC ended their financial support, which angered many people.
Then Liberia had an Ebola epidemic and US bank Citigroup decided to provide for the chimps, until the NYBC and the Humane Society International agreed to take care of the chimps.
Chimpanzees live up to 60 years and these chimps can't return to the wild.
This means many years of care.
