The California ground squirrel, also known as the Beechey ground squirrel, is a common and easily observed ground squirrel of the western United States and the Baja California Peninsula; it is common in Oregon and California and its range has relatively recently extended into Washington and northwestern Nevada. Formerly placed in Spermophilus, as Spermophilus beecheyi, it was reclassified in Otospermophilus in 2009, as it became clear that Spermophilus as previously defined was not a natural (monophyletic) group. A full species account was published for this species in 2016.
Spermophilus is a genus of ground squirrels in the squirrel family. As traditionally defined the genus was very species-rich, ranging through Europe, Asia and North America, but this arrangement was found to be paraphyletic to the certainly distinct prairie dogs, marmots, and antelope squirrels. As a consequence, all the former Spermophilus species of North America have been moved to other genera, leaving the European and Asian species as true Spermophilus.
The European ground squirrel, also known as the European souslik, is a species from the squirrel family, Sciuridae. It is among the few European species in the genus Spermophilus. Like all squirrels, it is a member of the rodent order. It is to be found in eastern and central Europe from southern Ukraine, to Asia Minor, Austria, the Czech Republic, Slovakia, Serbia, Greece, Romania, Bulgaria, North Macedonia and north as far as Poland but the range is divided in two parts by the Carpathian Mountains.
The saxaul sparrow is a passerine bird of the sparrow family Passeridae, found in parts of Central Asia. At 14–16 centimetres (5.5–6.3 in) and 25–32 grams (0.88–1.13 oz), it is among the larger sparrows. Both sexes have plumage ranging from dull grey to sandy brown, and pale brown legs. Females have less boldly coloured plumage and bills, lacking the pattern of black stripes on the male's head. The head markings of both sexes make the saxaul sparrow distinctive, and unlikely to be confused with any other bird. Vocalisations include a comparatively soft and musical chirping call, a song, and a flight call.
The Bhutan giant flying squirrel, also known as the Gray's giant flying squirrel or noble giant flying squirrel, is a species of rodent in the family Sciuridae. This species lives in Himalayan forests and it is one of the largest flying squirrels. Like other flying squirrels, it is mainly nocturnal and able to glide long distances between trees by spreading out its patagium, skin between its limbs.
The Tien Shan birch mouse is a species of rodent in the family Sminthidae. It is found in China, Kazakhstan and Kyrgyzstan.
The tropical ground squirrel is a species of rodent in the family Sciuridae. At one time the species was originally described as Spermophilus adocetus, but the genus Spermophilus was revised and subdivided in 2009 and it was placed in the genus Notocitellus. It is endemic to arid upland areas and deciduous woodland in Mexico. It is locally referred to as Cuinique.
The Alashan ground squirrel is a species of squirrel. It is native to China and Mongolia.
The Daurian ground squirrel is a species of rodent in the family Sciuridae. It is found in China, Mongolia, and Russia.
The red-cheeked ground squirrel is a species of rodent in the family Sciuridae. It is commonly referred to as the red-cheeked ground souslik and there are several recognized subspecies. It is found in central Asia. Spermophilus brunnescens, Spermophilus heptneri and Spermophilus ungae are accepted as synonyms. There is some controversy over whether Spermophilus pallidicauda and Spermophilus brevicauda should be regarded as synonyms or full species.
The yellow ground squirrel is a large and sturdy ground squirrel species native to Afghanistan, China, Iran, Kazakhstan, Turkmenistan, Uzbekistan and Russia. It inhabits sandy steppes with Artemisia, glasswort and tamarisk.
The russet ground squirrel is a species of rodent in the family Sciuridae. It is also known as the hibernating large ground squirrel and the large-toothed souslik. It is found in west central Asia where its natural habitat is temperate grassland.
The little ground squirrel or little souslik, is a species of rodent in the family Sciuridae. It is found from Eastern Europe to Central Asia.
The relict ground squirrel is a species of rodent in the family Sciuridae. It is found in Kazakhstan, Kyrgyzstan and Uzbekistan. It is thought to be synonymous with Spermophilus ralli, whose name was formerly used for the Tian Shan ground squirrel.
The Asia Minor ground squirrel, also known as Anatolian souslik, Anatolian ground squirrel, is a species of rodent in the family Sciuridae. It is found in Armenia, Iran, and Turkey. The scientific name roughly translates as "seed-lover with yellow underparts".
Spermophilus brevicauda is a species of rodent in the family Sciuridae. It is found in eastern Kazakhstan and the northern half of the Xinjiang region of China.
The pallid ground squirrel is a species of rodent in the family Sciuridae. It is found in Mongolia and the adjacent Nei Mongol autonomous region.
