Field Mouse Diet

Field mice are opportunistic omnivores, which means their diet can vary widely depending on the availability of food sources. They primarily feed on seeds, nuts, fruits, and grains, making them common in agricultural areas where these resources are abundant. Insects, larvae, and small invertebrates also form part of their diet, especially when plant-based food is scarce. During the autumn, field mice gather and store food in their burrows to ensure they have enough to eat throughout the winter months. This behavior is not only crucial for their survival but also helps in seed dispersal, inadvertently aiding the growth of new plants. Their feeding habits can lead to conflicts with humans, particularly farmers, as they can cause significant damage to crops and stored grains. However, their role in controlling insect populations and aiding in plant propagation highlights their importance in the ecosystem, balancing their impact on both natural and human environments.
