}} The Gambian sun squirrel (Heliosciurus gambianus) is a species of rodent in the family Sciuridae. It is found in Angola, Benin, Burkina Faso, Central African Republic, Chad, Democratic Republic of the Congo, Ivory Coast, Eritrea, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Liberia, Nigeria, Senegal, Sierra Leone, Sudan, Tanzania, Togo, Uganda, and Zambia. Its natural habitat is wooded savanna. TaxonomyThe Gambian sun squirrel was first described by the Irish naturalist William Ogilby in 1835 as Sciurus gambianus. It was designated the type species of the genus Sciurus after the International Commission on Zoological Nomenclature decided to suppress the use of the Sciurus annulatus for this purpose in 1957. The species was later reallocated to the genus Heliosciurus.[3] It is probably a species complex of several described species.[2] DescriptionThe Gambian sun squirrel has a head-and-body length of between {{convert|170|and|240|mm|in|1|abbr=on}} and a tail of between {{convert|180|and|260|mm|in|1|abbr=on}}. The pelage 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.[4] Distribution and habitatThe 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.[4] It also inhabits plantations and other cultivated areas.[2] StatusThe 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 has assessed its conservation status as being of "least concern".[2] References1. ^{{cite book|last1=Thorington|first1=R.W., Jr.|last2=Hoffmann|first2=R.S.|year=2005|pages=754–818|editor1-last=Wilson|editor1-first=D.E.|editor2-last=Reeder|editor2-first=D.M|url=http://www.bucknell.edu/msw3|chapter=Family Sciuridae|chapterurl=http://www.bucknell.edu/msw3/browse.asp?s=y&id=12400001|title=Mammal Species of the World: a taxonomic and geographic reference|edition=3rd|publisher=The Johns Hopkins University Press|isbn=0-8018-8221-4|oclc=26158608}} {{S.
