Pygmy rabbit is North America’s smallest rabbit and the only one that digs its own burrow system rather than relying on other animals’ holes, a trait tied directly to its dependence on tall, dense sagebrush for both food and cover. Its 13 Wyoming records, concentrated near the Red Desert and Seedskadee National Wildlife Refuge, come from a near-even split of iNaturalist and GBIF sources, a thin count that matches its status as a habitat specialist rather than a rare-but-widespread animal.

NatureServe ranks the species S2, Imperiled, in Wyoming, reflecting real concern over sagebrush loss to development and fire rather than just sparse documentation. What little seasonal signal exists clusters in early summer, but with records this few the pattern shouldn’t be read as a reliable activity calendar.
