Miller’s Langur^[1] (Presbytis canicrus), also called the Kutai Gray Langur or Miller’s Grizzled Langur, is the rarest of the four Hosei subspecies, all of which are native to the island of Borneo.

• Males weigh between 6 and 7 kilograms, while females weigh between 5.5 and 6 kilograms.

• The upper part of the face is black, while the lower part is whitish, with the whitish part forming a U under the nose.

• One of the world’s most endangered primates, Miller’s langur, was once considered extinct until it was rediscovered in 2013.
• It usually lives in groups of 5-12, including 1 adult male, with an average group size of 8 monkeys.
• It is sympatric with two other leaf monkeys of the Presbytis genus, the white-fronted surili, and the maroon leaf monkey.
• It is diurnal and arboreal, spending most of its time in the middle to upper canopy.
• Although this langur is known to display a calmer demeanor than other primates in its responses and gestures towards conspecifics, competition within groups has been observed.
