Natural Shelters:
* Tree cavities: This is their primary shelter, where they nest, raise young, and escape predators. They prefer cavities high up in trees, often in dead or decaying trees.
* Drey: A drey is a nest built of twigs, leaves, and moss, usually located in the fork of a tree or on a thick branch. They use dreys for resting and raising young, especially when tree cavities are scarce.
* Burrows: While not as common as tree cavities, red squirrels can use burrows, especially in areas with limited trees. They might occupy abandoned burrows dug by other animals, or even create their own.
Man-made Shelters:
* Nest boxes: Specially designed nest boxes can provide shelter for red squirrels, especially in areas with limited tree cavities.
* Fallen trees: Sometimes red squirrels will take refuge under fallen trees, especially during harsh weather conditions.
Factors Affecting Shelter Needs:
* Predator pressure: Areas with high predator pressure (e.g., hawks, owls, weasels) require more secure and well-concealed shelters.
* Climate: In colder climates, red squirrels need well-insulated shelters to survive harsh winters.
* Availability of resources: Areas with limited tree cavities or suitable nesting materials may require additional shelter options.
Importance of Shelter:
* Protection from predators: Shelter provides vital protection from predators like hawks, owls, and weasels.
* Raising young: Squirrels need safe and secure places to raise their young, which are especially vulnerable to predators.
* Weather protection: Shelter offers protection from extreme weather conditions, like rain, snow, and wind.
* Rest and sleep: Red squirrels need comfortable and safe places to rest and sleep, especially during the winter months.
Overall, red squirrels need a variety of shelter options to thrive. By providing suitable shelter, we can help ensure the survival and well-being of this fascinating species.
