The world’s oldest gorilla has turned 60. Colo was the first gorilla to be born in captivity anywhere in the world, when she arrived at the Columbus Zoo in Ohio in 1956.
She has outlived the average life expectancy for female gorillas in human care by over two decades.
Friends and fans flocked to visit Colo and sing “Happy Birthday”, and Colo’s keepers marked the occasion by decorating her cage, and gave her vegetable cake and presents.
