Texas bison sightings cluster tightly around the Panhandle’s canyon country: Caprock Canyons State Park, home to the official Texas State Bison Herd descended from Charles Goodnight’s original stock, and Palo Duro Canyon a short drive north. Muleshoe National Wildlife Refuge extends the pattern onto shortgrass prairie further west. Those three places anchor almost all of the state’s 820 records, which says as much about where wildlife watchers go in a state this large as it does about where the animals actually range.

Reports cluster around March and November, more likely a reflection of ranger-led herd tours and cooler visiting weather than a real seasonal swing in bison movement. With 820 records, bison sit in the common bucket among Texas mammals, though NatureServe hasn’t published a Texas-specific rank for a species that survives here mostly as managed herds rather than a self-sustaining wild population.
