Callosciurus
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
Bangladesh
and southern China.[1] Several of the species have settled on islands. In total, the genus contains 15 species and numerous varieties and subspecies.[1] The genera Glyphotes, Rubrisciurus, and Tamiops
Tamiops
have sometimes been included in Callosciurus. Species[edit] There are approximately 15 species in this genus,[1] and over 60 subspecies. These squirrels range in length from 13 to 27 cm (5.1 to 10.6 in), not including the tail which is often about the same length as the body.[2][3] Most are rather dull olive-brown to gray and several have a pale and dark stripe on their side, however a few are very colorful.[2] The Pallas squirrel may have an unremarkable olive-gray back, while its belly is often –but not always– bright red.[4] The "typical" subspecies of Prevost's squirrels have black backs, white sides, and red-brown undersides. The Finlayson's squirrel occurs in numerous varieties, three of which are overall red-brown, overall black, or pure white.[2] Most squirrels in Callosciurus
Callosciurus
live in tropical rain forests, but some individuals live in parks and gardens in cities. In the trees, they build their nests out of plant material. They are solitary, and give birth to one to five young. Their food consists of nuts, fruits, and seeds, and also of insects and bird eggs.

Anderson's squirrel
Anderson's squirrel
( Callosciurus
Callosciurus
quinquestriatus) is made up of two subspecies, C. q. quinqestriatus andC. q. imarius.[5] This species is found throughout China
China
and Myanmar, but is listed as "Near Threatened" by the IUCN
IUCN
due to habitat loss.[6] The black-striped squirrel ( Callosciurus
Callosciurus
nigrovittatus) 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.[5] It is listed as "Near Threatened" by the IUCN.[7] The Borneo black-banded squirrel
Borneo black-banded squirrel
( Callosciurus
Callosciurus
orestes) is endemic to northern Borneo, and listed as "Least Concern" by the IUCN.[8] The ear-spot squirrel ( Callosciurus
Callosciurus
adamsi), endemic to northern Borneo, listed as "Vulnerable" by the IUCN.[1][9] The inornate squirrel ( Callosciurus
Callosciurus
inornatus) is distributed across Laos, Vietnam, and the Chinese province of Yunnan. This squirrel was once considered a subspecies of Callosciurus
Callosciurus
pygerythrus, and as a result several texts inaccurately cite C. pygerythrus as being found in these areas.[10] The reclassification was based on different fur characteristics, placing it closer in relation to C. caniceps.[10][11] It is listed as "Least Concern" by IUCN.[10] The Kinabalu squirrel
Kinabalu squirrel
( Callosciurus
Callosciurus
baluensis), endemic to northeastern Borneo, specifically the wide area around Mount Kinabalu.[1] Its tail and upperparts are grizzled blackish, the underparts are reddish-orange, and the flanks have a narrow buff stripe with a broader black stripe below.[3] This species is listed as "Least Concern" by the IUCN.[12] Kloss's squirrel
Kloss's squirrel
(C. albescens), endemic to northern Sumatra, population data is insufficient to assess its endangerment status according to the IUCN.[1][13] It is debated whether it is a subspecies of C. notatus, which would make Kloss's squirrel
Kloss's squirrel
instead be named C. notatus albescens. Mentawai squirrel ( Callosciurus
Callosciurus
melanogaster) is one of 20 or so species native to the Mentawai Islands
Mentawai Islands
off the west coast of Sumatra. It is further dived into three subspecies: C. m. melanogaster, C. m. mentawi, and C. m. atratus.[5] This small isolated population is listed as "Vulnerable" by the IUCN
IUCN
due to habitat loss.[14] Phayre's squirrel
Phayre's squirrel
( Callosciurus
Callosciurus
phayrei) is found in China
China
and southern Myanmar, it listed as "Least Concern" by the IUCN.[1][15] The plantain squirrel ( Callosciurus
Callosciurus
notatus), is also one of several species called the oriental squirrel or tricolored squirrel. It is found in Indonesia, Malaysia, Singapore and Thailand, in a wide range of habitats: forests, mangroves, parks, gardens, agricultural areas. Prevost's squirrel
Prevost's squirrel
( Callosciurus
Callosciurus
prevostii), or Asian tri-colored squirrel, is found in forest in the Thai-Malay Peninsula, Sumatra, Borneo
Borneo
and nearby smaller islands, with an introduced population in northern Sulawesi. Pallas's squirrel
Pallas's squirrel
( Callosciurus
Callosciurus
erythraeus), also known as the red-bellied tree squirrel, is a species of squirrel native to Greater China, India, and Southeast Asia. Finlayson's squirrel
Finlayson's squirrel
( Callosciurus
Callosciurus
finlaysonii, misspelled C. finlaysoni) or the variable squirrel is found in Cambodia, Laos, Myanmar, Thailand, and Vietnam. Grey-bellied squirrel
Grey-bellied squirrel
( Callosciurus
Callosciurus
caniceps) consist of six subspecies found in forests, plantations and gardens in Peninsular Malaysia, Thailand, southern Myanmar, southern China
China
(Yunnan) and possibly western Laos.[16] The Irrawaddy squirrel ( Callosciurus
Callosciurus
pygerythrus) is made up of seven subspecies found throughout Bangladesh, China, India, Myanmar, and Nepal.[5][17]
