* Trees: This is the most common shelter for many monkey species. They use tree cavities, dense foliage, and even build nests in branches.
* Rock formations: Some monkeys, especially those living in rocky areas, will utilize caves or crevices for shelter.
* Abandoned burrows: Monkeys might occasionally use burrows left behind by other animals like badgers or foxes.
* Hollow logs: Monkeys may find refuge within the hollow interiors of fallen logs.
* Man-made structures: In some areas, monkeys may utilize abandoned buildings, sheds, or even cars for shelter.
It's important to note that monkeys are often opportunistic and will use whatever shelter is available in their environment.
