Round-tailed ground squirrels (Spermophilus tereticaudus) live in desert areas of the southwest United States and Mexico, including Arizona, California and northern Mexico. They feed on insects. They live in individual burrows but it is suspected that the squirrels living close together are related. Squirrels hibernate during the winter, emerge during mid-January, and reproduce in mid-March. An average of 3 young per litter are produced. Juveniles are first seen in early May. Squirrels will estivate during the hot dry summer months. |

In order to identify individual squirrels from a distance, animals are uniquely marked. Squirrels are captured in metal box live traps and transferred to a soft cloth-handling cone. There they are examined for general health, weight and size measurements are taken. The squirrels are then fitted with ear tags, which are like self-piercing earrings that have a unique identification number and color pattern. A DNA sample is also taken to determine the squirrel’s relatedness to other squirrels in the monument.
After tagging, round-tailed ground squirrels can be identified and observed from a distance. Individual squirrels are observed for a given length of time and a record of their behaviors are made. Movements are also recorded so that home range size and dispersal patterns can be determined.
