The variegated squirrel (Sciurus variegatoides) is a tree squirrel in the genus Sciurus found in Costa Rica, El Salvador, Guatemala, Honduras, southern Mexico, Nicaragua, and Panama. Fifteen subspecies are recognised.{{MSW3 Sciuridae | id = 12400203 | page = 764 | heading = Sciurus (Sciurus) variegatoides}} It is a common squirrel and the International Union for Conservation of Nature has rated it a "least-concern species". Variegated squirrels kept as pets in Germany have been implicated in the transmission of a bornavirus to humans from which three people have died.{{Cite journal|last1=Hoffmann|first1=Bernd|last2=Tappe|first2=Dennis|last3=Höper|first3=Dirk|last4=Herden|first4=Christiane|last5=Boldt|first5=Annemarie|last6=Mawrin|first6=Christian|last7=Niederstraßer|first7=Olaf|last8=Müller|first8=Tobias|last9=Jenckel|first9=Maria|last10=van der Grinten|first10=Elisabeth|last11=Lutter|first11=Christian|date=2015-07-09|title=A Variegated Squirrel Bornavirus Associated with Fatal Human Encephalitis|journal=New England Journal of Medicine|volume=373|issue=2|pages=154–162|doi=10.1056/NEJMoa1415627|issn=0028-4793|pmid=26154788|doi-access=free}}
Description
The variegated squirrel is a medium-sized squirrel; the head-and-body length is about {{convert|260|mm|in|1|abbr=on}} with a tail of much the same length. It weighs about {{convert|500|g|oz|0|abbr=on}}.{{cite book|author1=Thorington, Richard W. Jr.|author2=Koprowski, John L. |author3= Steele, Michael A. |author4=Whatton, James F. |title=Squirrels of the World|url=https://books.google.com/books?id=7PeYX8PwBxUC&pg=PT70 |year=2012 |publisher=JHU Press |isbn=978-1-4214-0469-1 |pages=70–73}} The several subspecies differ in appearance and there is often a considerable variation between the appearances of individuals in the same population. The dorsal colouration varies between dark brown to yellowish grey. The neck tends to be darker than other parts and there is often a paler patch behind the ears. The underparts are usually some shade of cinnamon. The tail is long and densely bushy; in Mexico it is black, sometimes with white tips to the hairs giving it a frosted appearance. In Nicaragua and Costa Rica, some individuals have pale underparts and tails.{{cite book|author=Ceballos, Gerardo |title=Mammals of Mexico |url=https://books.google.com/books?id=UrvxBQAAQBAJ&pg=PA184 |year=2014 |publisher=JHU Press|isbn=978-1-4214-0843-9 |pages=184–185}}
Distribution and habitat
This squirrel is native to Central America, its range extending from Mexico southwards through Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica and Panama. Habitats in which it occurs include both dry deciduous forest and evergreen forest, secondary growth, and plantations, and it can become a crop pest. It is mainly a lowland squirrel, ranging up to an altitude of {{convert|1800|m|ft|-1|abbr=on}}, or somewhat higher in Costa Rica.

Ecology
The species is diurnal and seldom descends to the ground; it spends the night in a nest it builds which is sometimes in a hole in a tree but more often is constructed of leaves and built in the fork of a branch close to the trunk. This squirrel is primarily a seed-eater, but also consumes fruits and some animal matter in the form of insects and nestlings. It tends to avoid hard shelled seeds but does consume acorns. Unlike some other squirrels in colder climates, it does not hoard food and therefore plays little part in the dispersal of seeds.
Status
S. variegatoides has a wide range and is a common species. No particular threats have been identified and the population seems steady, so the International Union for Conservation of Nature has rated its conservation status as "least concern".
