There’s a baby boom on Macaque Island! The Japanese macaques welcomed yet another new addition! Mom Rikka, age 12, has given birth to the 12th member of the troop — a newborn born on June 14. This is the fourth offspring for Rikka and the animal care team shares that both mom and baby are doing well. The sex of the second baby has yet to be determined, but adding another infant has not changed anything within the troop dynamics — the group is spending time together and socializing normally.

Rikka and her baby can be seen on the outside habitat most of the time — she is fluffier than the troop’s other new mom, Usagi, so if you are visiting Macaque Island to check out the two new babies, that might help you tell them apart.

The father is Kota, age 10, and this baby is the second offspring for Usagi and the eleventh member of the macaque troop. The animal care team shares that all is going very well with the baby, and they will remain hands-off. The sex of the baby is still undetermined.

The baby — a newborn — primarily nurses and sleeps on mother Usagi and will start to venture off mom within the first few months of age. Guests may be able to spot him or her tucked in Usagi’s chest or groin area while she sits on the rockwork in the habitat.

Macaques typically labor for a few hours, with the birth being quite quick. Usagi gave birth on her own without any help from her troop members. The troop dynamics continue as usual while giving space to Usagi and her baby.

Guests can view the new addition daily on Macaque Island. If he or she isn’t seen outside, mother Usagi could be taking a quick rest indoors.
