may have an unremarkable olive-gray back, while its belly is often –but not always– bright red.Smith, T. S., and Y. Xie, editors (2008). ''A Guide to the Mammals of China.'' 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. 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.
