Now that he's experienced sunshine, grass and trees, Willie B. will get a chance to learn about the birds and the bees.

The sheltered lowland gorilla, who spent 27 years caged up with a spare tire and a television set, will be placed in a menage a trois with two female gorillas from the Yerkes Regional Primate Research Center, according to a deal worked out by Zoo Atlanta.

It will be the first major social move for the 30-year-old gorilla, who hasonly experienced outdoor life for less than a year. He was moved into an outdoor habitat last year.

Officials hope that, over the next few months, Willie B. will learn how to relate to other gorillas and, with a little luck, make his first addition to the world's ape population.
