Japanese macaques, or snow monkeys, are totally open-minded when it comes to choosing a partner. Scientists consider them bisexual in orientation because they often choose same-sex partners even when presented with viable opposite sex-alternative. Substance over mate-ability, that’s what I always look for in a monkey.
Much like Roy and Silo, two griffon vultures named Dashik and Yehuda, built a life together at the Jerusalem Biblical Zoo. They engaged in an open an energetic sex life and even raised a chick together. But this love story doesn’t have a happy ending. A few years later, Yehuda left his partner for a woman. Dashik suffered a severe depression and had to be moved to another zoo, where he eventually fell in love with a woman.
