The Memphis Zoo says a bonobo ape was born there on Mother's Day.
The zoo said Tuesday that the bonobo was born to parents "Kiri" and "Mofana" on May 12, but the sex of the baby is not yet known. Zookeepers and veterinarians will determine the sex of the youngster in coming weeks.
Bonobos are a member of the greater ape family and look similar to chimpanzees. Matt Thompson, the zoo's director of animal programs, says bonobos are very rare in the wild and in captivity, and are a high conservation priority.
The zoo says all females in the bonobo group, including the mother and aunts, play a role in raising the babies.
It is the second bonobo birth at the zoo.
