The yellow-throated squirrel (Sciurus gilvigularis) is a tree squirrel in the genus Sciurus endemic to South America. It is found in Brazil, Guyana and Venezuela.
Sciurinae is a subfamily of squirrels, uniting the flying squirrels with certain related tree squirrels. Older sources place the flying squirrels in a separate subfamily (Pteromyinae) and unite all remaining sciurids into the subfamily Sciurinae, but this has been strongly refuted by genetic studies.
The western gray squirrel is a tree squirrel found along the western coast of the United States and Mexico. In some places, this species has also been known as the silver-gray squirrel, the California gray squirrel, the Oregon gray squirrel, the Columbian gray squirrel and the banner-tail. There are three geographical subspecies: Sciurus griseus griseus ; S. g. nigripes ; and S. g. anthonyi.
The genus Sciurus contains most of the common, bushy-tailed squirrels in North America, Europe, temperate Asia, Central America and South America.
The Brazilian squirrel is a tree squirrel in the genus Sciurus endemic to South America. It is found in southeastern Colombia, Brazil, Guyana, French Guiana, Suriname and Venezuela.
The Bolivian squirrel is a tree squirrel that is endemic to South America. Little is known of the species, which may represent a species complex.
The northern Amazon red squirrel is a squirrel species from South America. It occurs in Brazil, Colombia, Ecuador, Peru and Venezuela.
The Mexican gray squirrel is a tree squirrel in the genus Sciurus native to Guatemala and eastern and southern Mexico. It has been introduced to the Florida Keys.
Allen's squirrel is a tree squirrel in the genus Sciurus endemic to northern Mexico. It has no recognised subspecies.
The Caucasian squirrel or Persian squirrel, is a tree squirrel in the genus Sciurus found in temperate broadleaf and mixed forests in south-western Asia.
The Arizona gray squirrel is a tree squirrel, in the genus Sciurus, endemic to the canyons and valleys surrounded by deciduous and mixed forests in eastern Arizona and northern Mexico.
Collie's squirrel is a tree squirrel in the genus Sciurus endemic to Mexico.
The fiery squirrel is a rodent in the family Sciuridae. The taxon is endemic to the area south of the Orinoco River in the state of Bolívar, Venezuela.
The red-tailed squirrel is a species of tree squirrel distributed from southern Central America to northern South America.
The Japanese squirrel is a tree squirrel in the genus Sciurus endemic to Japan. It was described by Dutch zoologist Coenraad Jacob Temminck in 1844. The Japanese squirrel's native range includes large portions of the islands of Honshū, Shikoku, and Kyūshū. The Japanese squirrel is absent from Hokkaido, where it is replaced by the related red squirrel, which is conversely absent from the rest of the Japanese archipelago outside Hokkaido. Recently, populations in south-western Honshū and Shikoku decreased, and those on Kyūshū disappeared. One of the factors affecting the recent local extirpations of this species seems to be forest fragmentation by humans.
Peters's squirrel is a tree squirrel in the genus Sciurus endemic to Mexico. It was first described by the German naturalist and explorer Wilhelm Peters in 1863. Three subspecies are recognised. It is a common species, and the IUCN has rated its conservation status as being of "least concern".
The Andean squirrel is a tree squirrel endemic to Colombia where it inhabits montane rain forest and cloud forests of the Cordillera Occidental and Cordillera Central ranges of the Colombian Andes, at elevations between 2,000 and 3,300 metres. It is a small species with a body length of about 14 cm (6 in) and a similar length tail. It has soft, silky, reddish-brown fur, a darker tail and yellowish-grey underparts. It is thought to be diurnal but has been little studied, and the International Union for Conservation of Nature has rated its conservation status as being data deficient.
The Junín red squirrel is a species of squirrel from Peru and Ecuador.
Richmond's squirrel is a poorly known tree squirrel in the genus Sciurus endemic to Nicaragua, which is likely a synonym of the red-tailed squirrel. It is locally known as the ardilla del rama.
Sanborn's squirrel is or was a little known tree squirrel described in 1944 from the skin and skeleton of a single female specimen collected in Peru in 1941. Subsequently, over the proceeding years only a handful of either specimens were collected, or observations were recorded, in the regions of Madre de Dios and northern Puno in Peru, and Pando department in Bolivia. The 2019 IUCN assessment describes it as endemic to Peru. In 2015 this taxon was synonymised with Notosciurus pucheranii ssp. boliviensis. Its habitat is tropical dry broadleaf forests at elevations up to 570 m. It is considered possibly rare and potentially vulnerable to deforestation, but its population trend is not established.
The variegated squirrel 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. 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.
