Field Mouse Diet

The diet of a field mouse is diverse and highly adaptable, allowing it to thrive in various environments. Field mice are primarily herbivores, with seeds, grains, and fruits forming the bulk of their diet. They have a particular affinity for grass seeds and cereal grains, which are abundant in the wild and agricultural fields. Additionally, they enjoy nuts and berries when available, especially during the autumn months when these food sources are plentiful.

Insects and small invertebrates also play a role in the field mouse’s diet, particularly when plant-based food is scarce. They will eat beetles, caterpillars, and worms, which provide a rich source of protein. Field mice are also opportunistic feeders, meaning they will consume what is available in their environment, including plant stems, leaves, and even fungi. During colder months, they store food in their burrows to ensure they have enough to eat when foraging becomes more challenging. This adaptability in their diet is one of the reasons why field mice can live in such a wide range of habitats, from forests and fields to urban areas.
