found: Wikipedia, Mar. 21, 2020(The ground squirrels are members of the squirrel family of rodents (Sciuridae), which generally live on or in the ground, rather than trees. The term is most often used for the medium-sized ground squirrels, as the larger ones are more commonly known as marmots (genus Marmota) or prairie dogs, while the smaller and less bushy-tailed ground squirrels tend to be known as chipmunks. Together, they make up the "marmot tribe" of squirrels, Marmotini, and the large and mainly ground squirrel subfamily Xerinae, and containing six living genera. Well-known members of this largely Holarctic group are the marmots (Marmota), including the American groundhog, the chipmunks, the susliks (Spermophilus), and the prairie dogs (Cynomys). Subtribes and genera: Sciurotamias (Chinese rock squirrels); Subtribe Tamiina: chipmunks (might be full tribe): Eutamias, Neotamias, Tamias; Subtribe Marmotina: marmots: Marmota, Ictidomys: Thirteen-lined ground squirrel and related species; Subtribe Spermophilina: true ground squirrels: Ammospermophilus, Cynomys (prairie dogs), Spermophilus)
found: Squirrels, via National Geographic website, Mar. 21, 2020(Common Name: Squirrels. Scientific Name: Sciuridae. Tree squirrels are the types most commonly recognized, often seen gracefully scampering and leaping from branch to branch. Other species are ground squirrels that live in burrow or tunnel systems, where some hibernate during the winter season. Ground squirrels eat nuts, leaves, roots, seeds, and other plants. They also catch and eat small animals, such as insects and caterpillars. ... Flying squirrels are a third, adaptable type of squirrel. They live something like birds do, in nests or tree holes, and although they do not fly, they can really move across the sky. Flying squirrels glide, extending their arms and legs and coasting through the air from one tree to another) - https://www.nationalgeographic.com/animals/mammals/group/squirrels/
