What behavior do deer mice exhibit regarding their habitat?

Deer mice are primarily nocturnal creatures, meaning they are most active during the night and tend to remain hidden during the day to avoid predators and conserve energy. This behavior is an adaptive survival strategy, allowing them to forage for food under the cover of darkness while reducing the risk of being spotted by their natural enemies.

The other options suggest behaviors that do not align with the known habits of deer mice. For instance, they are not limited to building nests only in trees; their nesting can occur in a variety of locations that provide adequate cover. Additionally, while deer mice may live in urban areas, they are not known to primarily forage there, as they typically inhabit forests, grasslands, and more rural environments. Migration to warmer climates is also not characteristic of deer mice, as they generally do not migrate but rather adapt to seasonal changes in their local environments.
