a walk-through bird aviary featuring the critically endangered Bali starling, as well as Java sparrows, pied imperial pigeons and purple-naped lories . Phase two opened later in the summer and includes Sumatran tigers, Sunda gharials, and other reptiles (such as tentacled snakes and brown tortoises), birds (Javan rhinoceros hornbills, and Indonesian songbirds) and invertebrates. That phase including Monsoon Forest is now complete and open with the installation of the Sumatran orangutans and the arrival of a breeding pair of Javan silvery gibbons in December 2015. A third phase for Islands opened in summer 2017. The third phase included new exhibits for Malayan sun bear, Palawan binturongs, Malayan tapir, and a new songbird aviary featuring various birds from Indonesia as well as the critically endangered Javan green magpie. The magpies are, sometimes, off-show and replaced by sumatran laughingthrush. An exhibit for dusky pademelons and Goodfellow's tree-kangaroo was completed and opened in May 2018, alongside enclosures for cloud rats and Prevost's squirrels.

The new Monsoon Forest continues to be themed around the rainforests of South East Asia and features a large free-flight bird area exhibiting many species of South East Asian bird.

The most famous of these was Jubilee (1977–2003), so named as he was born in 1977, the year of the Queen's Silver Jubilee.
