What is a "bonnet monkey"?

The bonnet monkey, also known as the capped langur, is a primate species native to South Asia, recognized for their distinctive appearance characterized by a dark-colored body, a lighter-colored "cap" on their head, and a long tail. They primarily feed on leaves, fruits, and flowers, and are highly arboreal, spending much of their time in trees. Bonnet monkeys are known for their social behavior, typically living in close-knit groups, and are considered an important species in the ecosystems they inhabit.
