Spermophilus – Susliks

When they're not busy digging or foraging, they love to sunbathe on rocks or their burrow mounds

Ground squirrels are particularly notable for their burrowing habits, which play a significant role in aerating the soil and aiding in water penetration. These burrows, which they dig using their strong, sharp claws, are not just homes but intricate networks that provide safety from predators and harsh weather conditions. The structure of their burrows can be quite complex, featuring multiple entrances and chambers for nesting and food storage.

One of the most interesting aspects of ground squirrels is their diet, which is primarily herbivorous. They feed on a variety of seeds, nuts, fruits, and green vegetation, but some species also incorporate insects and other small animals into their diet. This varied diet helps control different plant and insect populations, contributing to ecological balance. Ground squirrels are particularly known for their habit of standing upright on their hind legs to survey their surroundings while foraging, a posture that has endeared them to many observers.

Socially, ground squirrels exhibit a range of behaviors from solitary to highly social, depending on the species. Some live in close-knit colonies where they communicate through a variety of sounds and gestures, helping each other watch for predators and locate food. These social structures also play a role in the breeding season, during which mating behaviors can be observed as males compete for females’ attention.

Ground squirrels are known for their hibernation habits. They are among the few mammals that enter true hibernation, which can last several months, depending on the climate. During this period, their body temperature drops, and their metabolic rate decreases significantly to conserve energy. The ability to hibernate is crucial for surviving winter when food is scarce and temperatures are low.
