The T. longicaudatus, commonly known as the Long-tailed Pocket Mouse, is a nocturnal rodent found in arid regions of North America. It has a distinctively long tail used for balance and communication. This small mammal feeds primarily on seeds and plays a crucial role in seed dispersal, contributing to its desert ecosystem.

The species T. longicaudatus, commonly known as the Long-tailed Vole, is native to North America. Its geographical distribution includes the western United States, extending from Alaska and western Canada down through California, Nevada, and New Mexico.

The Long-tailed Vole typically inhabits areas with temperate climates. It favors moist environments such as meadows, marshes, and the edges of forests. It is often found in areas with dense vegetation that provides cover and food sources.

The Long-tailed Vole occupies an ecological niche as a herbivore, feeding primarily on grasses, seeds, and roots. It plays a role in seed dispersion and serves as prey for various predators, including owls, hawks, and small mammals. Its habitat preferences can vary slightly with regional adaptations, where some populations may be found in drier areas with adequate vegetation cover.
