Rock squirrels earn their name honestly: Texas’s 4,415 records concentrate at Big Bend National Park, Guadalupe Mountains National Park, and the Davis Mountains, all cliff, boulder, and canyon-wall country where this ground squirrel dens in rock crevices and forages along talus slopes.
Records climb through spring, peaking in April and staying strong into May before easing off through a quieter winter. That rise fits a diurnal, sun-loving squirrel becoming more active as temperatures warm, though spring hiking traffic at these popular parks almost certainly boosts the count too.
With 4,198 of the 4,415 records coming from iNaturalist, this is one of the more heavily photographed rodents in the Trans-Pecos, easy to spot sunning itself on an exposed rock. NatureServe rates it secure statewide, consistent with a range that extends well beyond the handful of parks that generate most of its documented sightings.
