White-tailed Prairie Dog range [1]

The white-tailed prairie dog (Cynomys leucurus) is found in western Wyoming and western Colorado with small areas in eastern Utah and southern Montana. The largest populations are in Wyoming where they are known colloquially as "chiselers". [3] This prairie dog species lives at an elevation between 5,000 and 10,000 feet (1,500 and 3,000 m), generally a higher elevation than other prairie dog species. Its predators include black-footed ferrets, badgers, and golden eagles.

The white-tailed prairie dog is tan-brown in color, with large eyes and a dark patch on their cheeks above and below each eye. [4] This prairie dog species weighs between 28–53 oz (790–1,500 g), while having a length between 12–16 in (30–41 cm). [5]

Behavior

White-tailed prairie dogs display Interspecific competition with the Wyoming ground squirrel. When the squirrel enters the territory of the prairie dog, the white-tailed prairie dog chases the squirrel. Rarely does the prairie dog capture and kill the squirrel, but when it does, it leaves the squirrel for avian predators, as the prairie dog is an herbivore. Female white-tailed prairie dogs who killed squirrels had increased litter sizes, but the higher her body count, the lower her chances of surviving each subsequent attack. [6] White-tailed prairie dogs are diurnal, being the most active in the morning and afternoon. This species also hibernates in the winter seasons within their burrows and emerge to the surface when warmer seasonal changes occur. Male white-tailed prairie dogs emerge in late February to early March, while the female white-tailed prairie dog emerges roughly 2–3 weeks later. [5]

Diet

White-tailed prairie dogs are herbivorous, feeding mainly on grass, forbs, and sedges, primarily forbs. [7]

Lifestyle

White-tailed prairie dogs have a complex social system and live in colonies. This species uses visual signals and barks for communication. On average, each colony has 6 different "clans" or families. These families forage together for food and resources. The female white-tailed prairie dogs and their pups are sedentary, meaning they stay close to or inside the burrow, while the male seeks the food. [5]

Conservation status

White-tailed prairie dog populations have decreased dramatically, and the remaining population occupies only around 8% of their original range. It is subject to population controls by humans (shooting and poisoning), and threatened by a disease called Sylvatic Plague that can infect all prairie dogs. This animal lives in small communities that are vulnerable to being wiped out by all of these issues. This species appears in the IUCN Red List of Threatened Species, with a status of least concern, last assessed in 2016. [1] Petitions have been made to protect the white-tailed prairie dog, but they have been denied by the United States Fish and Wildlife Service due to insufficient scientific data describing current population trends. [8] This denial is being reconsidered, because former deputy assistant secretary Julie MacDonald has been found to have improperly influenced the scientific basis of the denial. Groups such as the Biodiversity Conservation Alliance are working to legally protect this species. [9]

<span class="mw-page-title-main">Prairie dog</span> Genus of ground squirrels

Prairie dogs are herbivorous burrowing ground squirrels native to the grasslands of North America. There are five recognized species of prairie dog: black-tailed, white-tailed, Gunnison's, Utah, and Mexican prairie dogs. In Mexico, prairie dogs are found primarily in the northern states, which lie at the southern end of the Great Plains: northeastern Sonora, north and northeastern Chihuahua, northern Coahuila, northern Nuevo León, and northern Tamaulipas. In the United States, they range primarily to the west of the Mississippi River, though they have also been introduced in a few eastern locales. They are also found in the Canadian Prairies. Despite the name, they are not actually canines; prairie dogs, along with the marmots, chipmunks, and several other basal genera belong to the ground squirrels, part of the larger squirrel family (Sciuridae).

<span class="mw-page-title-main">Burrowing owl</span> Species of owl

The burrowing owl, also called the shoco, is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other open, dry area with low vegetation. They nest and roost in burrows, such as those excavated by prairie dogs. Unlike most owls, burrowing owls are often active during the day, although they tend to avoid the midday heat. Like many other kinds of owls, though, burrowing owls do most of their hunting during dusk and dawn, when they can use their night vision and hearing to their advantage. Living in open grasslands as opposed to forests, the burrowing owl has developed longer legs that enable it to sprint, as well as fly, when hunting.

<span class="mw-page-title-main">Antelope squirrel</span> Genus of rodents

Antelope squirrels or antelope ground squirrels of the genus Ammospermophilus are sciurids found in the desert and dry scrub areas of the southwestern United States and northern Mexico. They are a type of ground squirrel and are able to resist hyperthermia and can survive body temperatures over 40 °C (104 °F).

<span class="mw-page-title-main">Ground squirrel</span> Type of ground-dwelling rodent

Ground squirrels are rodents of the squirrel family (Sciuridae) 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 or prairie dogs, while the smaller and less bushy-tailed ground squirrels tend to be known as chipmunks.

<span class="mw-page-title-main">Franklin's ground squirrel</span> Species of rodent

Franklin's ground squirrel is a species of squirrel native to North America, and the only member of the genus Poliocitellus. Due to the destruction of prairie, the populations of Franklin's ground squirrel have dwindled, approaching levels of concern. Its decline in the eastern portion of its range is mostly attributed to habitat fragmentation.

The swift fox is a small light orange-tan fox around the size of a domestic cat found in the western grasslands of North America, such as Montana, Colorado, New Mexico, Kansas, Oklahoma and Texas. It also lives in southern Manitoba, Saskatchewan and Alberta in Canada, where it was previously extirpated. It is closely related to the kit fox and some mammalogists classify them as conspecific. However, molecular systematics imply that the two species are distinct. Interbreeding between the two species does occur where their ranges overlap, but this hybridization is quite restricted in scope.

The Thunder Basin National Grassland is located in northeastern Wyoming in the Powder River Basin between the Big Horn Mountains and the Black Hills. The Grassland ranges in elevation from 3,600 to 5,200 feet, and the climate is semi-arid. The Grassland provides opportunities for recreation, including hiking, sightseeing, hunting, and fishing. There are no developed campgrounds; however, camping is allowed. Land patterns are very complex because of the intermingled federal, state, and private lands.

<span class="mw-page-title-main">Black-tailed prairie dog</span> Species of rodent

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 sq mi (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.
