 Photo: J. N. Stuart |  Colorado Chipmunk(Tamias quadrivittatus, Neotamias quadrivittatus)Family: Sciuridae (Squirrels, Chipmunks, Marmots, and Prairie Dogs) Size: 8.1 - 9.4 in (21 - 24 cm) Status: native; common Habitat: pine forests, alpine and subalpine habitats, prairies, shrub and brushlands, prefers higher elevations Typical location: Los Alamos The Colorado Chipmunk is larger than the Least Chipmunk and when it vocalizes it sways its tail side-to-side rather than up-and-down like the Least Chipmunk. Colorado Chipmunks are territorial and solitary except during the breeding season. They feed on a variety of plant materials and potentially insects. They will collect food in autumn to cache for winter. Although, these chipmunks do climb trees they are primarily ground dwellers often living in rocky areas in burrows.

 Photo: Phil Armitage | Least Chipmunk(Tamias minimus, Neotamias minimus)Family: Sciuridae (Squirrels, Chipmunks, Marmots, and Prairie Dogs) Size: 6.6 - 8.9 in (17 - 23 cm) Status: native; common Habitat: pastures, piney woods, rocky cliffs, coniferous forests, brushlands, prefers lower elevations Typical location: Los Alamos Tamias minimus is the smallest and most wide spread chipmunk species in North America. Least Chipmunks are diurnal and eat plant materials (seeds, berries, nuts and fruits) and insects. They often built and use nests in trees during the summer months. However, during the colder months they live in a simple burrow. They spend winter in a state of torpor, waking occasionally to eat food stored in the burrow or from nearby caches. The Least Chipmunk is very agile and communicates with a series of chipping sounds while flicking its tail up-and-down. Tracks Info Photos Distribution |
