The Orang-utan is one of the great apes and the largest arboreal (living among the trees) mammals found on earth today. There are two species of orang-utan, Sumatran and Bornean. They are a highly intelligent species known to solve complex problems, using tools and planning for tasks in advance. Orang-utans are solitary animals rarely meeting others of their species unless mating; they live for on average for 35years in the wild and 60 years in zoos.

Zoos breeding programs play an important role in species’ survival by increasing the diversity of their gene pool. The healthier and more diverse a specific population becomes the more opportunity there is of increasing population numbers and therefore lowering the possibility of extinction. 

Singapore Zoo has the world’s largest orang-utan enclosure and population. There are three separate enclosures. An island (which is a natural enclosure as orang-utans can’t swim); enclosed cages for breeding; and free range areas where large trees have been fitted with hot wire around their trunks stopping orang-utans from coming down the trunks and escaping. This allows for the primates to freely swing between trees throughout the zoo.   I am hoping to review Singapore Zoo in 2018
