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.[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 have sometimes been included in Callosciurus.
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's 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 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.
