- Mama, 59, had been matriarch at Royal Burgers Zoo, Arnhem in the Netherlands
- But in April 2016, she was terminally ill and refusing food and water while dying
- Then her old friend, Professor Jan van Hooff, came to see her and pay respects
- Once she noticed it was him, she reacted in pure delight and gave him a smile
This is the magical moment a dying chimpanzee recognises her old friend and gives him an emotional farewell.
Mama, the 59-year-old former matriarch at Royal Burgers Zoo in the Netherlands, was curled up in a ball and refusing food until the arrival of Professor Jan van Hooff, who she had known since 1972.
The terminally ill chimp, who was fast approaching the end of her life, can be seen reacting with pure joy when she realises who has come to see her.

Mama screeched with delight and beamed with a smile while greeting the professor
Screeching with pleasure and smiling in delight, Mama can be seen stretching out her hand and stroking Professor van Hooff’s head in greeting.
Initially she had not recognised him and persisted in her unresponsive behaviour.
Earlier in the video she can be seen refusing food and water as she lies in a weak state among hay.
But her bond with Professor van Hooff – who co-founded her chimp colony at the Arnhem zoo – was deep enough to shake her from her gloom.
