A western lowland gorilla sits in the grass in an undated photo taken the Republic of Congo. The Wildlife Conservation Society has tallied more than 125,000 western gorillas in two adjacent areas of the northern part of the Republic of Congo, which is the highest gorilla densities ever recorded, as high as eight individuals in an area smaller than half a square mile.

Zoo director Jeff Swanagan said Colo's keepers had been in a break room near the gorilla's habitat at the time of her brief escape.
"Colo apparently overheard them and decided to join the conversation," he said.
Swanagan said the gorilla exhibit was closed for about 45 minutes, a standard safety measure during an incident involving an animal.
