Colo's 60th birthday cause for celebration today at zoo

A milestone birthday will be celebrated today at the Columbus Zoo & Aquarium, complete with gifts, decorations and a "cake" made of tomatoes and apples. Colo, a Western lowland gorilla, turns 60 today. She is a celebrity, famous as both the first gorilla born in captivity and the oldest gorilla in captivity. Zoo officials mark Colo’s birthday annually, but this year's milestone is considered a special event.
