Great news for lonely heart orangutan Leo who has been living on his own on one of the islands in Samboj Lestari. He finally has some female company in the form of Mona, Elisa and Juminten, who were recently released on to the island to join him!

And that's not even the best bit........despite a long time in cages, within minutes of being on the island one of the girls started to build herself a nest! Natural instincts at their best!
