The Taiwan field mouse is a small rodent that lives only in the mountain forests of Taiwan. It has gray-brown fur, a long tail, and large ears, and it is active at night.
The Taiwan field mouse differs from close species by a longer tail and adaptation to cool mountain forests. It helps spread plant seeds and serves as food for snakes, birds, and small predators.
