A pale mutation in the ground squirrel: An Albinoid Color-phase in Citellus elegans Resembling the Recessive Cream Mutation in the Rat. Frank H. Clark and William L. Jellison, J Hered (1937) 28 (7), pages 259–260, doi : 10.1093/oxfordjournals.jhered.a104375
With twelve recognized subspecies, it ranges from southern Canada to northern Mexico, including most of the continental United States. The bobcat is an adaptable predator that inhabits wooded areas, as well as semi-desert, urban edge, forest edges and swampland environments. It persists in much of its original range and populations are healthy ...
Shorter burrows are dug as hiding places. This ground squirrel's home range is two to three acres (0.8 to 1.2 ha). Late in life, naturalist John James Audubon made a final expedition to the western plains in search of four-footed mammals. These striped ground squirrels would be tempting prey for many birds, especially hawks and owls.
Ground squirrels are rodents of the squirrel family that generally live on the ground or in burrows, rather than in trees like the tree squirrels.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 (genus ...
Richardson's ground squirrel (Urocitellus richardsonii), also known as the dakrat or flickertail, is a North American ground squirrel in the genus Urocitellus.Like a number of other ground squirrels, they are sometimes called prairie dogs or gophers, though the latter name belongs more strictly to the pocket gophers of family Geomyidae, and the former to members of the genus Cynomys.
The southern fox squirrel (Sciurus niger niger) is a close relative of the gray squirrel, which is one of the most common squirrel species in the country, and is considered to be the most variably ...
Urocitellus is a genus of ground squirrels.They were previously believed to belong to the much larger genus Spermophilus, but DNA sequencing of the cytochrome b gene showed that this group was paraphyletic to the prairie dogs and marmots, [2] [3] and could therefore no longer be retained as a single genus.
The yellow-bellied marmot (Marmota flaviventer), also known as the rock chuck, is a large, stout-bodied ground squirrel in the marmot genus. [2] It is one of fourteen species of marmots, and is native to mountainous and semi-arid regions of southwestern Canada and western United States, including the Rocky Mountains, Sierra Nevada, and the Great Basin, often (but not exclusively) living above ...
