Deer mice are small rodents commonly found in North America. They have a distinctive appearance, with a brown or grayish coat, white underbellies, and large eyes. These mice typically inhabit forests, grasslands, and even urban areas, where they build nests in burrows or hidden spaces. These animals are known for their agility and ability to climb. Deer mice are primarily nocturnal and feed on seeds, fruits, and insects. They play a crucial role in their ecosystems by dispersing seeds and serving as prey for various predators, including hawks and snakes.
