Hairless Chimp Jambo, the alpha male was born at Twycross Zoo in England. He has had alopecia, a form of hair loss since his youth. He was born on June 9, 1982.
In November 2018, Jambo lost his ear, possibly due to an accidental fight with his mother. Attempts to reattach it with skin glue failed as he continued to pick on it. In October 2022, he also lost a toe, with the cause unknown but possibly related to fights and agitation during mating season.
In 2018, the chimpanzees received a new habitat called "Chimpanzee Eden." It spans 1,160 square meters and includes two seven-meter-high indoor spaces connected to a large outdoor area with climbing frames and huts.
