A field mouse is a small rodent commonly found in fields and grassy areas. It has a brownish or grayish fur that helps it blend in with its surroundings. The field mouse is known for its agility and quick movements, allowing it to navigate through the tall grasses with ease. It primarily feeds on seeds, grains, and other plant material, making it an important part of the ecosystem's food chain. Despite its small size, the field mouse plays a significant role in dispersing seeds and contributing to soil health.
