Where does the house mouse, a mammal up to 8 cm long, live in its natural habitat? - briefly

The house mouse inhabits a variety of temperate environments, primarily residing in fields, grasslands, and the edges of woodlands where it can find shelter among vegetation, debris, and burrows. It also occupies human‑associated structures such as barns and sheds, which mimic its natural cover.

Where does the house mouse, a mammal up to 8 cm long, live in its natural habitat? - in detail

The house mouse (Mus musculus) occupies a broad range of natural settings across temperate and subtropical regions of Europe, Asia, and North Africa, with established populations in North America, South America, and Oceania due to accidental introduction. In its original range, the species favors open landscapes such as grasslands, shrublands, and agricultural fields where vegetation provides cover and abundant seed resources.

Within these ecosystems, individuals select microhabitats that offer shelter from predators and climatic extremes. Typical nesting sites include:

  • Burrows dug in loose soil, often near the base of perennial grasses or under fallen debris.
  • Crevices in rock outcrops, stone walls, and natural cavities in tree trunks.
  • Dense ground cover formed by leaf litter, tall herbaceous stems, or low shrubs.

Proximity to water sources—streams, irrigation channels, or damp soil patches—enhances survival, especially during dry periods. The mouse exploits a diet of seeds, grains, insects, and occasional plant material, so habitats rich in these food items are preferred.

Seasonal movements are limited; populations remain resident, adjusting activity patterns to temperature fluctuations. In winter, individuals retreat to deeper burrows or insulated crevices, while in summer they may occupy shallower nests to benefit from warmer ground temperatures.

Overall, the species thrives in environments that combine open foraging ground, structural complexity for concealment, and reliable access to water and food.
