The baby is the daughter of Rollie, a 16-year-old female, and Kwan, a 23-year-old male who also is the father of Patty, a female gorilla born in October to troop member Bana, according to a release from the zoo. The baby was born Friday—somewhat unexpectedly, as zookeepers had thought Rollie was more likely to give birth in December, said zoo spokeswoman Tiffany Ruddle.
The baby, which is not yet named, is a third-generation Lincoln Park Zoo resident. Her mother is the daughter of Kowali, 34, who also is part of the eight-member gorilla troop at the zoo.
The baby appears to be doing well, and Rollie is bonding well with her, zoo officials said in the release.
"We are encouraged by the bonding we already see between mom and baby," said Maureen Leahy, the zoo's curator of primates, in the release. "The two of them have been spending most of their time in a nest Rollie carefully crafted. The other individuals in the troop are interested, especially Bana and Patty, who are often close by."
Zoo members are to be given an advance look at the baby on Tuesday from 11 a.m. to 1 p.m. at the Regenstein Center for African Apes, with the public allowed in starting at 1 p.m. until 4:30 p.m., according to the release. The ape house will be open from 11 a.m. to 4:30 p.m. on Wedneseday and for the rest of the season.
