Seeing this Species


Phu Khieo Wildlife Sanctuary, Thailand

A group was habituated here at the Huai Mai Sot Yai study site [1].


Please see the page on the Grey Langur for more information on this sanctuary.


Probability of Success: Perhaps not bad if habituated


Overlapping species: Greater Slow Loris, Northern Pig-tailed Macaque, Rhesus Macaque, Stump-tailed Macaque, Grey Langur, White-handed Gibbon


*Perhaps surprisingly Long-tailed Macaque do not occur here, even though the park is home to the other four of Thailand's five species of macaque [1].
