Louisville zoo officials are expecting just the second gorilla birth in the zoo’s history in late March.Twenty-year-old Mia Moja is pregnant with her second offspring. The baby gorilla’s father is also a resident of the Gorilla Forest, 22-year-old Mshindi.General Curator Steve Wing says Mia hasn’t shown any pregnancy symptoms that are common to humans.“Animals in the wild, they have to mask all these special things," says Wing. "If they’re sick, if they’re pregnant and having – even if they feel bad – they mask it very well because that makes them prey for other things, even something as large as a gorilla.”Wing says once the baby gorilla is born, it will likely reside in Louisville for at least a couple of years.He says they’ll likely have some sort of community participation in naming the new gorilla.
