N'Yaounda, a western lowland gorilla at Hungary's Budapest Zoo, gave birth to a healthy baby on Jan. 5. The baby is N'Yaounda's first, and it's the first western lowland gorilla birth at the zoo in 10 years.

Of course, zoo staff are overjoyed about the new baby -- but they're also a bit distracted by a mystery surrounding its birth. See, two males -- Golo, a 30-year-old male, and his son, Ebobo, 10 -- both seem to think they're the baby's father. The zoo hopes that DNA testing will solve this gorilla paternity mystery, the Austrian Times reports.

"They both try to protect the mother and baby and both seem to believe it is their son -- which can only mean the mother N'Yaounda may have a bit of explaining to do when we get the results," one keeper told the newspaper. Zoo intrigue -- color us fascinated!
