Macaca leonina | Northern Pig-tailed Macaque | ลิงกังเหนือ [ling kạng h̄enụ̄x]


Good Spot: Khao Yai National Park, Pak Chong, Thailand




Macaca leonina is a monotypic species (no subspecies).

IUCN Conservation Status



The precise taxonomic boundary between Northern Pig-tailed Macaque and Southern Pig-tailed Macaque is not well defined. There are populations of the two taxa found on either side of the distribution limits in the Isthmus of Kra, but many of these populations are the result of release by humans. The two species hybridize in a small area of southern peninsular Thailand, as well as on the islands of Phuket and Yao Yai [1]. 

Seeing this Species


Northern Pig-tailed Macaque can be a bit more difficult to see than some other macaque species. They tend to stay in the forest. 


Khao Yai National Park in Pak Chong, Thailand 

Just three hours North of Bangkok, Khao Yai offers a good chance. We've seen them on mutliple trips there.
