Chicago’s Lincoln Park Zoo welcomed a new baby this weekend.
On August 18, a pair of Bolivian gray titi monkeys added a new member to their family, according to zoo officials.
The new arrival, who only ways a few ounces, is the ninth offspring for father Ocala, 15, and mother Delasol, 21, who is the oldest female in an accredited North America zoo to have successfully given birth. The parents and baby live together in the treetops with four older siblings: Suriqui, Madeira, Matzah and the youngest, Ocho, who was born last October.
Delasol is reportedly the oldest titi monkey to give birth in a North American zoo.
The baby’s gender remains unknown, as it spends most of its time attached to its mother’s back. Soon, other members of the family will begin sharing the load, carrying the little one up trees and over branches.
The little one’s arrival is a big deal, as the species’ population in the wild is on the decline. He/she is one of only about 50 of the species in U.S. zoos.
