The Cincinnati Zoo and Botanical Garden is celebrating its first gorilla birth since 1998.
The zoo said Muke, a 24-year-old western lowland gorilla, gave birth to a healthy baby late Sunday. Currently, the zoo is unsure of the gender of the baby gorilla.
Jomo, a 15-year-old silverback on loan from the Toronto Zoo, fathered the baby.
Samantha, a 36-year-old mother of six and grandmother of 11, is expected to deliver later in September.
Cincinnati Zoo's gorillas have been some of the most prolific in history, with the zoo reaching its 48th birth after Muke's delivery.
Cincinnati's breeding program had been on hiatus since 1999, when Chaka, a silverback on loan from Philadelphia and father of nine babies here, returned home. The zoo's other male, Colossus, never showed interest in breeding, and died in April.
Currently, the zoo has eight female gorillas and one baby at the Zoo's Gorilla World. The majority of the Cincinnati-born gorillas are living in zoos around the United States.
