A small social ground squirrel whose underground "towns" once covered hundreds of millions of acres. Their colonies are keystones supporting black-footed ferrets, burrowing owls, ferruginous hawks, and dozens more.
§ Quick facts
§ Encyclopedia
The black-tailed prairie dog is a rodent of the family Sciuridae found in the Great Plains of North America from about the United States–Canada border to the United States–Mexico border. Unlike some other prairie dogs, these animals do not truly hibernate. The black-tailed prairie dog can be seen above ground in midwinter. A black-tailed prairie dog town in Texas was reported to cover 25,000 mi2 (64,000 km2) and included 400,000,000 individuals. Prior to habitat destruction, the species may have been the most abundant prairie dog in central North America. It was one of two prairie dogs described by the Lewis and Clark Expedition in the journals and diaries of their expedition.

§ Identification
Field marks. Stocky cinnamon-brown ground squirrel with light belly; black-tipped tail (distinguishing feature); short rounded ears.
Similar species. White-tailed Prairie Dog (white tail tip, higher elevations). Gunnison's Prairie Dog (different range, smaller). Ground squirrels (smaller, no upright posture).
Voice. Famously complex alarm calls — high-pitched "yip-yip" with predator-specific variation.
§ Diet & behavior
Diet. Grasses, forbs, occasional insects; selective grazing maintains short-grass habitat that benefits many other species.
Behavior. Keystone species of shortgrass prairie. Colonies ("towns") historically covered 100+ million acres; reduced ~95–98% by poisoning, plague, and habitat conversion. Famously sophisticated alarm-call system — researchers have documented calls that encode predator type, size, color, and even speed; some scientists argue this represents genuine language. Burrow systems support 200+ associated species: black-footed ferrets (specialist predator), burrowing owls, ferruginous hawks, swift fox, mountain plover, prairie rattlesnake.
§ Range
Great Plains from southern Canada to northern Mexico
§ Habitat
Shortgrass and mid-grass prairies, on level to gently rolling ground
§ Threats
Habitat conversion to row crops, government and private poisoning programs, sylvatic plague.
§ Conservation status
According to the IUCN Red List, the black-tailed prairie dog is currently classified as Least Concern.
