Tropical Ground Squirrel (Notocitellus adocetus) lives in tropical dry forest across Central America. It feeds on seeds and fruits. Its conservation status is Least Concern.
Fascinating facts about the Tropical Ground Squirrel
- The tropical ground squirrel lives only in Mexico, confined to the Trans-Mexican volcanic belt that stretches across the State of Mexico, Guerrero, Jalisco and Michoacán. Its distribution reaches the highlands, with populations recorded at altitudes of up to about 3 000 m. Within this arid upland and deciduous woodland it occupies rocky canyons, cliffs and sparse vegetation. The species' range is therefore limited to a specific mountainous zone in central Mexico.
- The species constructs intricate burrow systems that can extend as far as 60 cm below the surface. These tunnels are dug beneath walls, under rocks or at the base of trees, providing shelter from predators and extreme temperatures. The depth allows the squirrel to store food and create nesting chambers safely underground. Such burrows are a hallmark of its social, diurnal lifestyle in the rugged terrain it inhabits.
- Each morning the squirrel forages between 09:00 and 11:00, gathering seeds and fruits that it stuffs into its cheek pouches. It then carries the cached food back to its burrow where it can eat it later, often storing it for periods of scarcity. This routine focuses on the early daylight hours when food is most abundant and predators are less active.
- In remote parts of its range the tropical ground squirrel is shy, keeping to its burrows and avoiding contact. When it lives close to people it becomes habituated and shows far more confidence, often sprinting away only when approached closely. It will perch on walls to watch human activity and may retreat into a crevice, peering out to monitor its surroundings. This change in behaviour reflects its flexible social and diurnal nature.
- On cultivated land the tropical ground squirrel can breed at any time of year, taking advantage of the constant food supply provided by crops. In contrast, within natural deciduous woodland it appears to restrict breeding to the period from May to June, just before the onset of the wet season. This seasonal timing likely aligns offspring birth with the peak availability of seeds and fruits. Such flexibility helps maintain its populations despite yearly fluctuations.

About the Tropical Ground Squirrel
In the scorching landscapes of its native habitat, the Tropical Ground Squirrel darts with reckless abandon, its tiny paws barely touching the sun-baked earth as it weaves a frantic path through the underbrush. With a twitching nose and alert, black-rimmed eyes, this diminutive creature navigates its world with a frenetic energy, driven by an insatiable quest for the seeds, fruits, and insects that sustain it. As it pauses, momentarily, to survey its surroundings, the Tropical Ground Squirrel's very existence seems a testament to the boundless resilience of life in the harshest of environments.
