Description
The Gambian sun squirrel has a head-and-body length of between and a tail of between . The pelage
Fur is a thick growth of hair that covers the skin of mammals. It consists of a combination of oily guard hair on top and thick underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as an insulating blanket ...
is variably coloured but is usually greyish with a grizzled appearance. There is a paler grey ring around the eye, and the throat and underparts are also pale. The tail is boldly ringed in black and white, there being about fourteen rings.
Distribution and habitat
The Gambian sun squirrel occurs across tropical Africa, its range extending from Senegal and the Gambia, to Ethiopia and Kenya. A separate population is further south in Angola and Tanzania. It inhabits wooded savanna and other grassland with scattered trees, moving through the branches but sometimes descending to the ground.[ It also inhabits plantations and other cultivated areas.][

Status
The Gambian sun squirrel is a common grassland species with a wide range and a presumed large total population. The population trend has not been evaluated but no particular threats have been recognised; it is able to adapt to habitats modified by humans and is present in a number of protected areas. For these reasons, the International Union for Conservation of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of nat ...

A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. T ...
