Callosciurus is a genus of squirrels collectively referred to as the "beautiful squirrels". They are found mainly in Southeast Asia, though a few species also occur in Nepal, northeastern India, Bangladesh and southern China. Several of the species have settled on islands. In total, the genus contains 15 species and numerous varieties and subspecies. The genera Glyphotes, Rubrisciurus, and Tamiops have sometimes been included in Callosciurus.
The mountain ground squirrel is a rodent that is native to southwestern Angola, western Namibia, and western South Africa. It is also known as the Kaoko ground squirrel or the Damara ground squirrel.
Finlayson's squirrel or the variable squirrel is a species of rodent in the family Sciuridae. It is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. The species occurs in a wide range of wooded habitats, including gardens and parks in cities like Bangkok. It was named in honour of the Scottish naturalist and traveller George Finlayson.
Prevost's squirrel or Asian tri-coloured squirrel is a colourful species of rodent in the family Sciuridae. It is found in forests in the Thai-Malay Peninsula, Sumatra, Borneo and nearby smaller islands, with an introduced population in northern Sulawesi. Although the Prevost's squirrel is declining in some regions because of habitat loss and hunting, the species is not considered threatened since it generally remains common and widespread. It can live in somewhat disturbed habitats and often visits plantations or gardens. It mostly feeds on plant material, especially fruits, but also takes insects.
The sculptor squirrel or Bornean pygmy squirrel is a species of rodent in the family Sciuridae. It was described by Michael Rogers Oldfield Thomas in 1898. It is monotypic within the genus Glyphotes. It is endemic to northern Borneo in Sabah and Sarawak (Malaysia) and inhabits areas elevated at 285–1,800 metres (935–5,906 ft).
The red-legged sun squirrel is a species of rodent in the family Sciuridae, also commonly known as the isabelline red-legged sun squirrel. It is native to tropical western and central Africa where its range extends from Senegal in the west, through Nigeria and the Republic of Congo to Uganda and Tanzania in the east. Its natural habitats are subtropical or tropical moist lowland forests and moist savanna. This species is thought to be common and has a very wide distribution, so the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Zanj sun squirrel is a species of rodent in the family Sciuridae found in eastern Africa.
The Central American dwarf squirrel, also known as Alfaro's pygmy squirrel, is a small tree squirrel in the genus Microsciurus and tribe Sciurini found in Colombia, Costa Rica, Nicaragua, and Panama. No species of squirrel within this genus are listed as endangered, however they are rarely seen because they are extremely elusive. This suggests that their population numbers may be larger than documented.
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.
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 cream-coloured giant squirrel or pale giant squirrel is a large tree squirrel in the genus Ratufa found in forests in the Thai-Malay Peninsula, Sumatra (Indonesia), Borneo and nearby small islands. The species is near threatened and vulnerable to habitat degradation, and it has probably been extirpated in Singapore where the last sighting was in 1995. Reported sightings in Vietnam in 1984 are considered to be dubious.
The tufted ground squirrel or groove-toothed squirrel is a species of rodent in the family Sciuridae. It is the sole species in the genus Rheithrosciurus. It is found only on the island of Borneo. Confirmed elements of its diet include nuts, seeds and insects, for which it has been filmed foraging on the forest floor.
The Andean squirrel is a tree squirrel endemic to Colombia where it inhabits montane rain forest and cloud forests of the Cordillera Occidental and Cordillera Central ranges of the Colombian Andes, at elevations between 2,000 and 3,300 metres. It is a small species with a body length of about 14 cm (6 in) and a similar length tail. It has soft, silky, reddish-brown fur, a darker tail and yellowish-grey underparts. It is thought to be diurnal but has been little studied, and the International Union for Conservation of Nature has rated its conservation status as being data deficient.
The Guayaquil squirrel is a tree squirrel endemic to Ecuador and Peru. It is a robust squirrel with a head-and-body length of 18 to 32 cm and a similar length tail. The colour is variable; in Peru, a pale morph is more common, while in Ecuador, most individuals have darker grey fur on the forequarters, dull orange hindquarters. A melanistic morph is sometimes seen. It lives largely in trees and is diurnal, feeding on seeds, flowers, and other plant material, fungi and some insects. These squirrels are also found in urban areas, living in close proximity to humans, and may be vectors for leptospirosis and Chagas disease. This squirrel faces no particular threats, has a wide range and is relatively common, and the International Union for Conservation of Nature has rated it as being of "least concern".
Brooke's squirrel is a species of rodent in the family Sciuridae. It is found in Indonesia and Malaysia. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss. It was named for Charles Brooke, the second White Rajah of Sarawak by Oldfield Thomas from a specimen collected by Charles Hose on Mt Dulit.
Sundasciurus is a genus of rodent in the family Sciuridae. It contains 20 species:
Low's squirrel is a species of rodent in the family Sciuridae. It is found in Borneo and nearby islets. Its former subspecies S. l. robinsoni from Sumatra and the Malay Peninsula and S. l. natunensis from the Natuna islands have recently been given species status.
The slender squirrel is a species of rodent in the family Sciuridae. It is arboreal and found in Indonesia, Singapore, Malaysia, and Thailand. The body is brown on the upper parts and light grey on the underparts. The body measures about 13–16 cm, with a slightly shorter slender tail. It feeds on soft bark, fruits and insects.
