What feature does the Deer Mouse's nesting behavior include?

The Deer Mouse is known for its adaptability in nesting behaviors, which includes nesting in various natural environments, such as trees and stumps. This behavior allows them to utilize natural shelters that provide safety and protection from predators as well as harsh weather conditions. By nesting in such locations, Deer Mice can take advantage of the resources available in wooded areas while also being concealed from potential dangers.

The other choices present nesting behaviors that are not consistent with the habits of Deer Mice. For instance, nesting primarily in open fields doesn't provide the necessary cover and protection that these mice prefer. Similarly, the use of metallic materials in nest-building does not align with their natural behaviors; Deer Mice typically gather natural materials such as grasses, leaves, and other plant fibers. Lastly, while they may occasionally nest in human structures, it is not an exclusive behavior, making the idea of them only building nests within homes too restrictive. This reflects their broader ecological adaptability.
