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.

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 news (do feel free to send news articles that you write to be included here)
