Distribution

Cliff chipmunks live in the Western United States and Mexico. They range from Idaho south through Arizona and western New Mexico in the United States. In Mexico, their range extends from Sonora and western Chihuahua to northeastern Sinaloa and northwestern Durango. Cliff chipmunks typically live along cliff walls or boulder fields bordering Pinyon-juniper woodlands. They also inhabit montane forests of Ponderosa pine and spruce, oak woodlands, riparian vegetation, and desert shrublands. A common destination for spotting these chipmunks are the cliffs of the Grand Canyon.

Habits and Lifestyle

Cliff chipmunks are generally solitary. They can be territorial around their dens and chase others. Females although can be gregarious, and form feeding groups. Around 10 chipmunks may gather at a food source, and slowly travel together while foraging, keeping a distance betwen individuals. In these aggregations, they may communicate vocally to identify themselves, or to maintain spacing. Cliff chipmunks are diurnal being active mostly during the day. They are very agile, and can often be seen scaling steep cliff walls. These small creatures like to take dust baths and groom their heads and tails. Cliff chipmunks live in dens and nests which they make in rocky bluffs and cliffs. Sometimes they can use underground burrows and tree nests. These chipmunks may migrate seasonally depending to availability of food.
