Habits and Lifestyle

Speckled ground squirrels are diurnal creatures which hibernate from October to April. They are active in the morning once the sun warms the area slightly and then come back to their underground den during the heat of the day. Late in the day they come out again for another feeding bout. These ground squirrels live in separate burrows within a larger colony. These colonies can be up to over 160 individuals per ha. When outside their burrows these small animals spend a most of their time standing on their hind legs scanning the surroundings in search of predators. They use alarm calls for a variety of purposes. Primarily, the alarm call is used to warn conspecific squirrels of predators and to alert predators that they've been detected.
