Second Newborn Gorilla Joins Troop at Lincoln Park Zoo

Chicago (June 13, 2019) Lincoln Park Zoo’s western lowland gorilla troop welcomed another new face June 12 at Regenstein Center for African Apes! Bana, 24, gave birth to a healthy infant, exactly one month after the arrival of a male infant, born to female Rollie, May 12.

The baby is staying tucked in close and clinging to Bana and has begun nursing. The infant is the second offspring for Bana, who gave birth to female Patty in 2012. Kwan, 30, the silverback of the family group, continues to closely watch Bana and the infant.

The unsexed newborn joins a troop of eight individuals, including adult females Bahati and Rollie, three juvenile females Bella, Nayembi, and Patty, and the recent male infant. Both gorilla infants have yet to be named.

“Having two offspring born close together provides such an exciting time for guests and gorillas alike,” said Moyse. “The infants will have the opportunity to grow, develop, and explore their surroundings together and learn from one another.”

Animal Care staff continue to closely monitor Bana and the infant as they continue to surpass critical milestones. Kwan and Bana were recommended to breed as a part of the Western Lowland Gorilla Species Survival Plan® (SSP), a collaborative effort among zoos accredited by Association of Zoos and Aquariums.

After Sunday, the building will be open intermittently. As the troop adjusts, the gorilla family group may not be visible indoors but will be visible when they explore their outdoor habitat. Lincoln Park Zoo Members can attend an exclusive members-only sneak peek June 15 and 16 from 10 a.m.–noon. Not a member? Visit to join.


Western lowland gorillas are critically endangered in their native Central Africa due to habitat loss and poaching. Scientists with Lincoln Park Zoo’s Lester E. Fisher Center for the Study and Conservation of Apes are dedicated to saving this species with ongoing work both at the zoo and in the Republic of the Congo. This work has facilitated new strategies to mitigate the impact of human and consumer behaviors such as unsustainable logging and urbanization.
