Where do Peromyscus mice typically build their nests?

Peromyscus mice commonly build their nests in underground cavities around the roots of trees or shrubs. This preference for nesting sites provides them with shelter and protection from predators and environmental elements. The underground cavities create a safe microhabitat that maintains favorable conditions for their young and allows easy access to food sources in the surrounding area.

While Peromyscus mice can occasionally nest in tall grass and bushes, or even in human structures, their primary choice tends to be the more concealed and secure underground environments. This nesting behavior is crucial for their survival, as it helps them evade threats and ensures a better chance of successful reproduction.
