We are sad to share that Kyle, a Bornean orangutan and beloved ambassador for his critically endangered species, passed away Jan. 10 from chronic respiratory disease. He was 28 years old. Although male orangutans do not take on parental duties, Kyle was one of his son Redd’s best playmates and served as a great adult male role model. LEARN MORE: . . . The primate team fondly remembers Kyle as a kind and gentle individual. While he has been in the Zoo’s care over the past 21 years, they watched him mature from a gangly juvenile to an adult with impressive cheek pads and boisterous displays and calls that echoed throughout the Great Ape House and Think Tank habitats. . . . Kyle contributed greatly to the community of orangutan caretakers’ knowledge of Bornean orangutans by voluntarily participating in the Zoo’s positive reinforcement training program. From the behaviors Kyle was trained to do, keepers were able to collect blood pressure readings, ECG readings and awake radiographs. Our Zoo community misses him dearly.
