Sciuridae is a family of small mammals in the order Rodentia and part of the Sciuromorpha suborder. Members of this family are called sciurids, and include squirrels, chipmunks, and marmots. They are found worldwide outside of Australia and Antarctica, primarily in forests, shrublands, and grasslands, though some species can be found in wetlands, deserts, or rocky areas. They range in size from the lesser pygmy flying squirrel, at 6 cm (2 in) plus a 6 cm (2 in) tail, to the Olympic marmot, at 75 cm (30 in) plus a 24 cm (9 in) tail. Sciurids primarily feed on fruit, seeds, and nuts, though many species also eat insects, fungi, bark, eggs, and small vertebrates. Almost no sciurids have population estimates, though fifteen species are categorized as endangered species and three—the Namdapha flying squirrel, Vancouver Island marmot, and speckled ground squirrel—are categorized as critically endangered.

The 284 extant species of Sciuridae are divided into five subfamilies: Callosciurinae, containing 67 species of Asian squirrels in 14 genera; Ratufinae, containing four species of giant squirrels in a single genus; Sciurillinae, containing only the neotropical pygmy squirrel; Sciurinae, containing 84 species of flying squirrel and tree squirrels in 20 genera; and Xerinae, containing 128 species of marmots, chipmunks, prairie dogs, and ground squirrels in 24 genera. A few extinct prehistoric sciurid species have been discovered, though due to ongoing research and discoveries, the exact number and categorization is not fixed.

Conventions

The author citation for the species or genus is given after the scientific name; parentheses around the author citation indicate that this was not the original taxonomic placement. Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the sciurid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted.
