Flying squirrels are a tribe of 50 species of squirrels in the family Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to glide from one tree to another with the aid of a patagium, a furred skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail.
Hylopetes is a genus of flying squirrels. There are about 10 species.
The groove-toothed flying squirrel or North Chinese flying squirrel is a species of rodent in the family Sciuridae. It is considered monotypic within the genus Aeretes. It is endemic to China, and occurs in Sichuan, Gansu, Hebei, and Beijing. Its natural habitat is temperate forests.
The black flying squirrel or large black flying squirrel is a species of rodent in the family Sciuridae. It is found in Brunei, Indonesia, and Malaysia; its habitat is primary and secondary forests and gardens where it uses tree hollows. It feeds on fruits, nuts and other vegetable matter. It is likely not threatened and is adaptable to habitat loss. Black flying squirrels tend to have smaller populations than other squirrels because female black flying squirrels breed infrequently and have a small litter size of just one young.
The black-striped squirrel is a species of rodent in the family Sciuridae. It is found throughout Java, Sumatra, southern Thailand, the Malay Peninsula, and numerous small islands. This taxon consists of four subspecies: C. n. nigrovittatus, C. n. bilimitatus, C. n. bocki, and C. n. klossi. It is listed as "least concern" by the IUCN.
The Kashmir flying squirrel is a species of rodent in the family Sciuridae. It is monotypic within the genus Eoglaucomys. It is found in Afghanistan, India and Pakistan. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. The Afghan flying squirrel is usually considered a subspecies.
The Afghan flying squirrel is a subspecies of rodent in the family Sciuridae. It is endemic to Afghanistan.
The Bartel's flying squirrel is a rodent species in the family Sciuridae endemic to West Java, Indonesia. It inhabits subtropical and tropical forest.
Swynnerton's bush squirrel, also known as Svynnerton's bush squirrel, is a species of rodent in the family Sciuridae endemic to Tanzania. Its natural habitat is subtropical or tropical moist montane forests.
The red and white giant flying squirrel is a species of rodent in the family Sciuridae. It is a very large, dark rufous-red, buff and white flying squirrel found in forests at altitudes of 800–3,500 m (2,600–11,500 ft) in mainland China and 1,200–3,750 m (3,940–12,300 ft) in Taiwan, although the population of the latter island is distinctive and likely better regarded as a separate species, the Taiwan giant flying squirrel. Additionally, the red and white giant flying squirrel possibly ranges into northeastern South Asia and far northern Mainland Southeast Asia. This squirrel has a wide range and is relatively common, and the International Union for Conservation of Nature lists it as being of "least concern".
Petaurista is a genus of rodent in the family Sciuridae. They are large to very large flying squirrels found in forests and other wooded habitats in southern and eastern Asia.
The spotted giant flying squirrel, also known as the lesser giant flying squirrel, is a species of rodent in the family Sciuridae. It is found in hill and mountain forests at altitudes of 200–4,000 m (660–13,120 ft) in Southeast Asia north to central China and the east Himalayan region, although the northern populations sometimes are regarded as separate species as the grey-headed giant flying squirrel, Chindwin giant flying squirrel and P. marica. Two of these, as well as a few other populations, lack the white spots on the upperparts for which it is named. Although a large flying squirrel, it is a relatively small giant flying squirrel.
Hodgson's giant flying squirrel is a species of rodent in the family Sciuridae. This large flying squirrel lives in Himalayan forests in Asia. Like other flying squirrels, it is nocturnal and able to glide long distances between trees by spreading out its patagium, skin between its limbs.
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 Indian giant flying squirrel, also called the large brown flying squirrel or the common giant flying squirrel, is a species of rodent in the family Sciuridae. It is capable of gliding flight using a skin membrane, the patagium, stretched between front and hind legs. It is found in mainland Southeast and South Asia, and southern and central China.
The Basilan flying squirrel is a species of rodent in the family Sciuridae. It is endemic to the Philippines. It is often confused with the mindanao flying squirrel.
The Siberut flying squirrel is a species of rodent in the family Sciuridae. It is endemic to Indonesia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The black giant squirrel or Malayan giant squirrel is a large tree squirrel in the genus Ratufa native to the Indomalayan zootope. It is found in forests from northern Bangladesh, northeast India, eastern Nepal, Bhutan, southern China, Myanmar, Laos, Thailand, West Malaysia, Cambodia, Vietnam, and western Indonesia.
The Himalayan striped squirrel, also known as western striped squirrel or Burmese striped squirrel, is a species of rodent in the family Sciuridae. It lives in a variety of forest from tropical to subtropical in Bhutan, Cambodia, China, India, Laos, Malaysia, Myanmar, Nepal, Thailand, and Vietnam. This species is diurnal, arboreal and feeds on fruit, vegetable matter, and insects. It often seen in small groups and uses tree holes for shelter.
The Mechuka giant flying squirrel is a species of rodent in the family Sciuridae. First described in 2007 from East Himalayan forests at altitudes of 1,500–2,500 m (4,900–8,200 ft) in the region of Mechuka of north-central Arunachal Pradesh in India, its taxonomic status and position is not fully resolved. it was originally described as P. nigra but has been replaced by mechukaensis because it was a primary homonym of P. nigra Wang 1981.
