Bonnie

Species	Orangutan
Breed	Hybrid Bornean/Sumatran
Sex	Female
Born	1976 (age 48–49)
Known for	Whistling
Residence	National Zoo in Washington, D.C.

She began spontaneously whistling, mimicking an animal caretaker making the sound. This is significant as whistling is a sound that is in a human's—but not an orangutan's—repertoire. While some "lower primates" have been shown to make non-standard sounds for their species, it has always been the result of intense training, whereas Bonnie picked up the new sound mechanism through imitation. Furthermore, she seems to whistle just because she likes the sound, as opposed to producing this behavior in response to a potential food reward. Bonnie's whistling was documented in the journal Primates by Dr. Serge Wich et al.^[2]
