Female koalas, when in captivity, can engage in lesbian behaviour.

Once in captivity, female koalas participate in lesbian orgies. According to scientists at the University of Queensland, who monitored 130 koalas using digital cameras, female koalas in captivity engage in homosexual acts three times as often as they participate in heterosexual activities. The orgies often include up to five females at a time.
