Oklahoma’s occurrence databases hold 269 records for the silky pocket mouse. Of the eight states in its range, Oklahoma holds the third-largest share of mapped records, behind only New Mexico and Colorado.
A western prairie mouse with sandy-soil ties
This is one of North America’s smallest seed-carrying rodents, and in Oklahoma it belongs to the mixed-grass and shortgrass prairie of the western part of the state and the Panhandle, where sandy soil lets it burrow easily and shrub cover gives it somewhere to hide from predators. It doesn’t turn up nearly as often in the wetter, heavier-soiled prairie and woodland further east.
Cheek pouches keep seeds dry
External, fur-lined cheek pouches let this mouse gather seeds without wetting them, an advantage in the dry grassland and shrub country it favors. It rarely needs to drink, since it pulls most of its water from the seeds it eats. Records peak in Jun and again in Aug–Sep, tracking the prairie’s main seed-set windows.
