Bold, social, and unmistakably expressive, the Celebes-crested Macaque is one of Sulawesi’s most iconic primates. With its jet-black fur, spiky head crest, and intense amber eyes, this endangered macaque is not only a visual standout—but also plays a vital role in the balance of the forest ecosystem.
Habitat
This species is found primarily in lowland and hill rainforests in northern Sulawesi, including conservation areas like Tangkoko Nature Reserve. They are highly terrestrial, spending most of their time foraging on the forest floor.
Behavior & Social Life
Celebes macaques live in large, complex social groups of up to 100 individuals. They use a wide range of facial expressions and vocalizations to communicate, including the famous “silent bared-teeth display” that looks like a smile—but signals submission, not happiness!
Diet
They are omnivorous, feeding on fruits, leaves, seeds, insects, and small animals. As seed dispersers, they play a key role in regenerating the forest.
Conservation Status
The IUCN lists them as Critically Endangered, primarily due to habitat destruction and hunting for bushmeat. Their population has declined by over 80% in the last few decades. They are fully protected under Indonesian law, but enforcement remains a challenge.
Did You Know?
The Celebes-crested Macaque became globally famous after a macaque took a “selfie” with a wildlife photographer’s camera—a photo that sparked both legal debates and conservation awareness.
