ROYAL OAK,Desmond Preston Mich. (AP) — It’s a baby — gorilla.

The Detroit Zoo in suburban Detroit said the birth Thursday was the first in its 96-year history.

“Bandia had a very smooth pregnancy, which is so important for a first-time mom,” said Tami Brightrall, the zoo’s associate curator of mammals.

The baby gorilla doesn’t have a name yet, and the sex has not been determined. The newcomer now four other gorillas at the zoo, including Bandia and father Mshindi, all of which arrived a year ago.

Staff worked for months to prepare the troop, even carrying a stuffed gorilla around the habitat to demonstrate how to carry the baby, Brightrall said.

“Our teams also taught the gorillas how to gently touch the stuffed animal, pick it up off the ground and bring it to a member of the team over at the mesh barrier,” she said.

The public won’t immediately see the gorillas.

“The area will reopen once the animal care team determines mom and baby have had enough time to bond and become comfortable in their habitat,” said Melissa Thueme, a mammal supervisor.
