Koko (gorilla)

Koko Born July 4, 1971 (age 44) San Francisco Zoo, US
Years active -1972–present
Known for Use of sign language
Hanabiko "Koko" (born July 4, 1971) is a female western lowland gorilla who is known for having learned a large number of hand signs from a modified version of American Sign Language (ASL).
Her trainer, Francine "Penny" Patterson, reports that Koko is able to understand more than 1,000 signs of what Patterson calls "Gorilla Sign Language" (GSL).[2] In contrast to other experiments attempting to teach sign language to non-human primates, Patterson simultaneously exposed Koko to spoken English from an early age. Reports state that Koko understands approximately 2,000 words of spoken English, in addition to the signs.[3] Koko's life and learning process has been described by Patterson and some of her collaborators in a number of books, peer reviewed articles, and on a website.
As with other great ape language experiments, the extent to which Koko has mastered and demonstrates these signs was disputed in a study published in 1999.[4] But it is generally accepted that she does not use syntax or grammar, and that her use of language does not exceed that of a young human child.[5][6][7][8][9]
Koko was born at the San Francisco Zoo and has lived most of her life in Woodside, California, although a move to a sanctuary on Maui, Hawaii, has been planned since the 1990s.[10] Koko is short for the name Hanabiko (花火子 literally "fireworks child"?) in Japanese, a reference to her date of birth, the Fourth of July. Koko also gained publicity when she reportedly adopted a kitten.
