The yellow-faced pocket gopher is a mammal in the Colorado record. Open occurrence databases hold just 2 recent Colorado records for it, one an iNaturalist photo and one a museum specimen. A burrowing animal that rarely surfaces leaves next to no photographic trace.

A gopher of the southeastern plains

The yellow-faced pocket gopher is a stout, powerfully built burrower with a broad head, big foreclaws, and a nearly bare tail, named for the warm buff wash across its face. It needs deep, workable soil, so in Colorado it belongs to the sandy and gravelly ground of the far southeast. Its two recent records come from Otero and Arapahoe counties, while older specimens place most of its known range in Las Animas, Baca, Pueblo, and Huerfano counties and the surrounding plains and river valleys.

A life spent underground

This gopher lives almost its entire life below the surface, cutting extensive tunnel systems with its claws and teeth, feeding on roots and tubers it reaches from below, and betraying its presence mainly through the fan-shaped mounds of fresh soil it pushes up. It works its burrows year-round and seldom emerges into the open. Because so few are ever seen alive, its Colorado record is a map of where people have trapped or happened to spot one rather than a measure of how often it appears, and long quiet stretches mark gaps in looking, not the animal’s absence.

Status in Colorado

NatureServe ranks the yellow-faced pocket gopher S4, apparently secure, in Colorado, G5 globally, and the IUCN lists it as least concern. It is native and not considered at risk, but its thin tally measures how completely it stays hidden: a common enough resident of the southeastern soils that almost never shows itself above ground.
