The oldest known gorilla in America has died.

FOX's Dave Anthony reports:

Colo made history back in 1956 becoming the first gorilla in the world to be born in a zoo. 60 years later:

"Happy Birthday to you!"

They threw her a birthday party at the Columbus Zoo in Ohio, that was back in December. On Tuesday, zoo officials say Colo died in her sleep, not long after a malignant tumor had been removed.

Colo far outlived typical captive gorillas by two decades. She was a mother of three and lived long enough to be a great great grandmother of three.

The zoo's president says Colo inspired people to help protect gorillas in their native habitat.
