Solitary Proboscis Monkey

Solitary Proboscis Monkey:

Proboscis monkeys tend to live in groups consisting of one alpha male, several females, and various mixed young. On the other hand, you can also often find groups made up solely of males. Finally, some proboscis monkeys prefer to live alone, particularly males. Unlike some primates, proboscis monkeys aren’t known to be territorial, and groups will frequently overlap with one another.
