ZSL London Zoo, May 25th 2017.  A gibbon looks for treats during a photocall to promote ZSL London's newest exhibit, a treehouse style enclosure that will open to the public on Saturday 27th of May. The exhibit is home to duo Jimmy and Yoda, that will take people on a journey high into the Northern white-cheeked gibbon’s (Nomascus leucogenys) treetop habitat, where they’ll be able to watch the pair swing gracefully through a maze of branches and ropes.
