Habitat
They primarily inhabit arid grasslands, shrublands, and open pine forests in the southwestern United States and northern Mexico. These squirrels prefer areas with loose, sandy soils suitable for burrowing and are often found at elevations up to 2,500 meters.
Diet
Merriam's ground squirrels eat a variety of seeds, nuts, green vegetation, and insects, with a focus on plant matter during the growing season. They forage actively during the day, particularly in the early morning and late afternoon, using their cheek pouches to store food for later consumption.
Behavior
These squirrels are diurnal and live in colonies with extensive burrow systems, exhibiting social hierarchies and cooperative behaviors. They are territorial around their burrows but can be seen basking in groups during warmer weather. Hibernation occurs from late summer through winter, with activity resuming in spring.
Conservation Status
Merriam's ground squirrel is classified as Least Concern by the IUCN, with a stable population trend. Major threats include habitat loss from urban development and agriculture, but they are not currently at risk.
