Brookfield, Ill.— A 6-month-old male orangutan is doing well in large part due to the dedicated animal care staff at Toledo Zoo, Milwaukee County Zoo, and Brookfield Zoo.
Kecil (pronounced Ka-cheel, which is Indonesian for little) arrived at Brookfield Zoo on June 20 to be introduced to a surrogate mom, Maggie, the zoo’s 53-year-old Bornean orangutan. Discussions among orangutan care experts from the AZA’s Orangutan Species Survival Plan (SSP) and Hand Rearing/Surrogacy Advisory Group as well as the three institutions resulted in the determination that Maggie could be a good surrogate mother because of her calm demeanor and her previous success in this role.
Upon his arrival at Brookfield Zoo, Kecil was given a brief physical examination and then taken to an off-exhibit area at the zoo’s Tropic World exhibit to be introduced to Maggie. Since the two have been together, animal care staff have seen very positive interactions. The two engage each other in play, and the young orangutan often sleeps in the crook of Maggie’s arm. He has shown interest in Maggie’s food, but for now he has been sampling softer foods like bananas, and baby cereal has become a staple. In addition, Kecil comes to the front of their enclosure on his own or with Maggie’s assistance to be bottle-fed, which will continue at least until he is a year old.
“Although it has been only a short time and we have a long road ahead of us, we are extremely optimistic due to Kecil and Maggie’s progress so far. Maggie is an easygoing and gentle orangutan. The two have been together since Kecil’s arrival, and Maggie has provided care and attention that he needs to receive from an orangutan.” said Jay Petersen, curator of primates and carnivores for the Chicago Zoological Society, which manages Brookfield Zoo.
Kecil was born on January 11, 2014, at Ohio’s Toledo Zoo. His mother, Yasmin, who has raised her own offspring in the past, showed little interest in caring for him following a difficult delivery. Toledo Zoo’s keepers and veterinary team worked tirelessly to offer the two private off-exhibit quarters, hoping that they would bond. However, after months of dedicated but unsuccessful efforts to encourage Yasmin to care for Kecil, they decided it would be best to place him with a surrogate at another zoo.
On May 19, at four months old, Kecil was taken to Milwaukee County Zoo to be placed with a possible surrogate named MJ. During the month Kecil was at Milwaukee, animal care staff worked around the clock to introduce Kecil to MJ, and the initial results were positive. However, the optimal level of bonding that staff had hoped to see was not achieved, and after various stages of progress, the situation seemed to have reached a plateau.
Once again, discussions took place to determine the next course of action for the infant. Because it is extremely important that Kecil be raised by orangutans rather than humans, the animal care experts decided to try another potential surrogate, and he was moved to Brookfield Zoo to be introduced to Maggie.
During the transfers to Milwaukee County Zoo and Brookfield Zoo, an animal care staff member from the previous facility accompanied Kecil to help in his transition. “Kecil seems calm and adaptable to the changing situations in his young life. The moves don’t seem to have fazed him at all” said Petersen. “We are all hoping that Brookfield Zoo will be his last move for a while.”
“The collaboration among the three institutions to ensure Kecil grows up in the best environment possible speaks to the commitment of everyone involved,” said Stuart Strahl, Ph.D., president and CEO of the Chicago Zoological Society.
It will be many months before Kecil and Maggie will be on exhibit for guests to see. Animal care staff want to give the two time to develop their relationship. In addition, Kecil needs to become much more agile and mobile before being introduced to the exhibit. In the meantime, the Chicago Zoological Society will be setting up a keeper journal atwww.CZS.org/Kecil where the public can get periodic updates, including photos and video, of the two.
Orangutans once lived over much of Southeast Asia, but their range and population have been dramatically reduced. Their natural habitat—the rain-forest islands of Sumatra and Borneo—continues to be decimated. Huge tracts of the rain forests are logged and converted to palm oil plantations. There are approximately 40,000 Bornean orangutans left in the wild, and the population has declined by 50 percent since 1990. Researchers predict that about 5,000 orangutans die every year and that if this current rate of decline continues the species will be extinct in the wild in the not too distant future.
The mission of the Chicago Zoological Society is to inspire conservation leadership by connecting people with wildlife and nature. The Chicago Zoological Society is a private nonprofit organization that operates Brookfield Zoo on land owned by the Forest Preserves of Cook County. Open every day of the year, the zoo is located off First Avenue between the Stevenson (I-55) and Eisenhower (I-290) expressways and is also accessible via the Tri-State Tollway (I-294), Metra commuter line, CTA, and PACE bus service.
