Archive: Male Chimpanzee Born at Detroit Zoo in January Successfully Unites with Adoptive Mom
Detroit Zoological Society animal care staff nurtured baby chimpanzee 24/7 for 5 Months

ROYAL OAK, Mich.,
Twenty-four hours a day, seven days a week for five months (and during a pandemic).
That’s how long the Detroit Zoological Society (DZS) animal care staff hand-reared a male chimpanzee born in early January before they successfully transitioned his care to an adoptive chimpanzee mom in June.
“It’s a story of great dedication,” said Scott Carter, chief life sciences officer for the Detroit Zoological Society. “Nights, weekends and through a pandemic —Detroit Zoo primate staff cared for the baby chimpanzee around the clock. And now it’s a very heartwarming story of a baby who has found a devoted, adoptive chimp mom and family.”
Zane was born on January 7, 2020, to Chiana, 26, who is also the mother of 6-year-old Zuhura. But soon after Zane’s birth, Chiana became very ill and was unable to care for her newborn. Chiana was treated by veterinarians and recovered, but after she recovered, she showed no interest in caring for her little son. The Detroit Zoo’s primate care staff stepped in to give Zane 24-hour care, which included carrying him constantly, as a mother chimp would, and teaching him to take milk from a bottle.
Over the five months, Zane lived in the Great Apes of Harambee building instead of a nursery so he could be around the other chimpanzees. During this time, the chimpanzees could see him up close through the mesh of their enclosure.
“Every day, the other chimpanzees could see us caring for him,” said Carter. “He was always near the other chimps even though they physically could not be together.”
To prepare Zane for life with the other chimpanzees, the Detroit Zoological Society consulted with the Association of Zoos & Aquariums’ Chimpanzee Species Survival Plan and other zoos that have integrated rejected infants into social groups. The carefully planned process began with observing potential surrogate moms in the Detroit Zoo’s 11-member chimpanzee troop and their responses to Zane. Mother-daughter duo Trixi, 50, and Tanya, 29, both adult females in the troop, showed interest almost immediately.
“Trixi is a confident and high-ranking matriarch,” said Carter. “She was a wonderful mother to her daughter Tanya, and when we were considering who could be the best new mother for Zane, she stood out. She was very interested in being near him whenever she could and seemed quite taken with him.”
From their first physical interaction, it was clear that 5-month-old Zane had found his new adoptive family.
“Zane approached and hugged Trixi and Tanya the minute he had the chance,” said Carter. “Trixi is Zane’s primary caregiver, while Tanya, who has never had a baby of her own, loves playing with Zane, napping with him, and carrying him for short periods.”
Carter added, “We’re incredibly proud of our devoted primate staff for doing such an amazing job of caring for Zane and preparing him and his new adoptive family to thrive together.”
Baby Zane is now living with the troop at the Great Apes of Harambee at the Detroit Zoo. The chimpanzees who live at the Detroit Zoo have a fission-fusion dynamic, which means they have the freedom to choose who they want to spend their time with at any given moment. As with all animals at the Detroit Zoo, they also have the choice to go where they please in the habitat, so Zane might not always be visible. The multi-acre indoor-outdoor Great Apes of Harambee habitat is home to 12 chimpanzees.
Zane’s birth is the result of a recommendation from the Association of Zoos & Aquariums’ Chimpanzee Species Survival Plan, a cooperative population management and conservation program that helps ensure the sustainability of healthy, genetically diverse and demographically strong captive animal populations. Chimpanzees are listed as endangered by the International Union for Conservation of Nature due to habitat loss, fragmented populations and illegal wildlife trafficking.
