Agile gibbons are found in Indonesia on the island of Sumatra, Malaysia, and southern Thailand.

While not commonly recognized as having subspecies, some recognize a mountain and lowland version.

Accurate numbers of these gibbons in the wild are hard to find, but declines of 50% are thought to have occurred in the last 45 years, so this species is also classed as endangered. 

 While the Bornean white bearded gibbon is now considered a separate species, I will deal with it on the same page as they are similar. This species is considered endangered. Should news on this species grow, we will separate it out from other species.

While these animals are not great apes, they are lesser apes, and are very interesting to watch. There are likely to be a great draw in places where Orangutans do not exist, such as on mainland Asia, as well as in smaller reserves that cannot support Orangutans.

This is not a species that I have written about, but if I do in the future, it will appear below. Furthermore, as we add destinations that are good for this species they will appear below the new

The Grey (Mullers/Southern, Northern, Western(Abbots) and Eastern) gibbon is a species endemic to the island of Borneo. As you can see, it goes by a variety of names.

Thought, until recently to be a single species, alongside the Northern and the Southern grey, recent studies have demonstrated that they are distinct enough to be separated either as subspecies or species. However, we are going to deal with them together. It is true that along the border of their ranges, there have been occasions of breeding together -and while lions and tigers have interbred, this seems different. It is possible that in the future, I will separate them out.

Borneon grey gibbons are as a whole considered endangered, having suffered a greater than 50% decline in numbers in the last 45 years.

The rainforests of Borneo are thought to be 140 million years old yet humans have destroyed half of it in just 40 years. The biggest driver of this deforestation is the Palm oil industry, which has required land to grow its crops. Never-ending growth of the lands for this crop must end, though whether this end will be reached while Borneon forests still stand is anyones guess.

Siamong gibbons live in the forests of Indonesia, Malaysia and Thailand. There are currently 2 recognized subspecies – one on the island of Sumatra, and the other in Malaysia. One place where the population is closely watched is in the Bukit Barisan Selatan National Park in Sumatra. Here the population was estimated to be around 22,390 individuals. This suggests that there could be hundreds of thousands of Siamang gibbon across its entire range

Estimates for the whole area are unknown, and so possible numbers vary wildly. Having said this, in 1980s an estimates of the entire population was thought to be 360,000. While it is likely to have reduced dramatically fallen in the last 40+ years, though even a 50% reduction leaves almost 200,000.

While these animals are not great apes, they are lesser apes, and are very interesting to watch. There are likely to be a great draw in places where Orangutans do not exist, such as on mainland Asia, as well as in smaller reserves that cannot support Orangutans.
