Orangutan Robin celebrates 40th birthday at Denver Zoo
Denver Zoo celebrated the birthday of male orangutan Robin, who turned 40-years-old on Sunday, March 27! This is a big milestone as the median age of Sumatran orangutans in zoos is 28. Zookeepers placed streamers and enrichment – including LEGOs – throughout his indoor exhibit. He also enjoyed fruits, veggies, seeds, nut butters, as well as a special birthday “cake” made of primate biscuits. Robin has lived in the Great Apes building in Primate Panorama since it opened in 1996 and is described by his keepers as having a sweet personality.
