Habitat
Proboscis monkeys primarily inhabit mangrove forests, riverine areas, and coastal swamps in Borneo. They prefer habitats near water sources for easy access to food and escape from predators. These environments include a mix of tall trees and flooded areas, making them semi-aquatic.
Diet
Proboscis monkeys mainly consume leaves, fruits, seeds, and flowers from mangrove trees, with a preference for young leaves that are easier to digest. They are folivorous and spend much of their day foraging in the canopy to avoid ground predators. Feeding activity peaks in the early morning and late afternoon.
Behavior
Proboscis monkeys live in groups called harems, typically consisting of one adult male, several females, and their offspring, with males defending the group territory. They are diurnal and arboreal, spending time in trees but also swimming proficiently across rivers. They exhibit social behaviors like grooming and use loud honking calls for communication and alarm.
Conservation Status
The IUCN classifies the Proboscis monkey as Endangered, with populations declining due to habitat loss from deforestation and palm oil plantations. Major threats include hunting and human encroachment.
