Cheracebus

These monkeys are native to the dense rainforests of northern South America, especially in countries like Brazil, Venezuela, Colombia, and parts of Peru. Cheracebus species tend to live in remote, often undisturbed forest regions, which makes them a bit more elusive compared to some of their titi monkey cousins. They are small to medium-sized primates, usually about the size of a domestic cat, and like other titi monkeys, they have long, bushy tails that aren’t prehensile but help with balance as they move among the treetops. Their fur coloration varies depending on the species, but most have rich hues of black, dark brown, or reddish tones, often paired with the lighter or contrasting “collar” that sets them apart visually.

Socially, Cheracebus monkeys follow the classic titi monkey lifestyle: quiet, family-focused, and full of strong social bonds. They live in small family groups, usually composed of a monogamous adult pair and their offspring. The bond between the parents is deep and long-lasting, and one of their signature behaviors is tail-twining—a sweet gesture where the pair wraps their tails around each other while sitting close. These monkeys also spend time grooming and staying physically close throughout the day.

Like other titi monkeys, Cheracebus species begin their mornings with a duet of vocal calls between the adult pair. These calls can be surprisingly loud and are used to strengthen pair bonds and communicate territory boundaries to neighboring families. Even though they’re not aggressive by nature, these calls are their way of saying, “We’re here—please keep your distance.” The songs are also a way to stay in touch with each other while moving through the forest canopy.
