Thirteen-lined Ground Squirrel
Slender ground squirrel striped with alternating pale lines and spots, often upright beside prairie burrows
Artwork inspired by Francis Lee Jaques
Thirteen-lined Ground Squirrels wear a remarkably orderly pattern of pale stripes alternating with rows of rectangular spots. They eat seeds and insects, sometimes tackling surprisingly large prey, then spend the coldest months in deep hibernation with dramatic reductions in body temperature and heartbeat.
Roadside verges, mown parks, cemeteries, campuses, and shortgrass sites are reliable in warm months. Scan low rather than into trees: an alarmed animal freezes upright, then dives into a burrow whose entrance may be hidden beneath short vegetation.

- Small rounded ears; context: short grass, lawns, roadsides, and grazed prairie
Read Thirteen-lined Ground Squirrel in four field decisions
- Shape
- Slender ground squirrel striped with alternating pale lines and spots
- Habitat
- Concentrate on short grass, lawns, roadsides, and grazed prairie.
- Behavior
- Search slowly in short grass, lawns, roadsides, and grazed prairie, then wait for normal activity to resume. During Daytime, April–October, still watching usually reveals more than pursuit.
- Evidence to record
- Treat the first impression as a lead, not a conclusion. Compare gait, tracks, feeding sign, body proportions, and behavior before recording Thirteen-lined Ground Squirrel.
Good to know
A close image of Thirteen-lined Ground Squirrel is not automatically decisive: habitat, timing, full structure, and the alternative species considered should remain part of the record.
