Coco is a female chimpanzee born around 1952. She moved to the zoo in 1961. In 2012, Coco died at the age of 60. At the time of her death she was the oldest animal at the Oregon Zoo and the second-oldest chimp in the U.S. zoo population.
Coco touched countless lives during the half-century she lived at the Oregon Zoo. She was always a favorite among visitors, and helped change the way zoo-born chimps are raised. Largely because of what researchers learned from Coco and the success of her offspring, young chimps in all AZA-accredited zoos are now kept with their mothers for at least three to five years. Two of her daughters – Delilah and Leah – will carry on Coco's legacy at the zoo.
Coco was a cherished friend, mother, and ambassador for her species.
