The northern Amazon red squirrel (Sciurus igniventris) is a squirrel species from South America. It occurs in Brazil, Colombia, Ecuador, Peru 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 red squirrel or Eurasian red squirrel is a species of tree squirrel in the genus Sciurus common throughout Europe and Asia. The red squirrel is an arboreal, primarily herbivorous rodent.
The fox squirrel, also known as the eastern fox squirrel or Bryant's fox squirrel, is the largest species of tree squirrel native to North America. Despite the differences in size and coloration, it is sometimes mistaken for American red squirrels or eastern gray squirrels in areas where the species co-exist.
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.
Striped ground squirrels form a taxon of squirrels under the subfamily Callosciurinae. They are only found in Southeast Asia. Species in this genus include:
The southern Amazon red squirrel, is a squirrel species from South America where it inhabits forests in much of north-western South America east of the Andes. Three subspecies are currently recognised. It is a dark red colour, or a dark brown grizzled with ochre, has whitish underparts and grows to a total length of 48 to 63 cm, including a very long tail. It spends much of its time on the ground in the undergrowth and feeds largely on nuts. Little is known of its breeding habits, but it is a sociable species, several individuals often feeding together in one tree. This squirrel faces no particular threats, has a wide range and is relatively common, and the International Union for Conservation of Nature lists it as a "least-concern species".
The yellow-throated squirrel is a tree squirrel in the genus Sciurus endemic to South America. It is found in Brazil, Guyana 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.
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 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.
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.
