Tamiasciurus hudsonicus
A small tree squirrel of North American conifer forest, with a reddish back, white belly and white eye ring, plus ear tufts in winter. It is strongly territorial and hoards conifer seeds.
The American red squirrel (Tamiasciurus hudsonicus) is a tree squirrel widespread in the boreal conifer forests of northern North America, favouring forests rich in conifer seeds and fungi with interlocking canopies. The back is reddish to olive-grey and the belly white or cream, separated in summer by a clear dark line. A white eye ring is present all year, and ear tufts grow in winter. The tail is smaller and flatter than in other tree squirrels. It is told from the Douglas squirrel by its pale belly (rusty in the Douglas squirrel) and the colour of its tail-hair tips. It is mainly diurnal and becomes active all day in autumn to prepare for winter shortages. It is strongly territorial and eats mainly conifer seeds, plus fungi, buds, flowers, fruit, sap, insects and birds' eggs. Wild animals average 5 years and reach 10; the captive record is 9. It belongs to a different genus from Japan's regulated invasive Pallas's and Eurasian red squirrels. In Japan, European captive-bred animals and others appear only occasionally at specialists.

Nomenclature follows global taxonomic authority databases.
Not covered by CITES or the specified-animal rules. As a member of the squirrel family, it needs a species-name certificate under the Invasive Alien Species Act when imported (it is not itself a designated or uncategorized invasive species). Tamiasciurus is a separate genus from Callosciurus and Sciurus, which contain designated and uncategorized invasive species. Imports fall under Japan's animal import notification system (Infectious Diseases Control Law, MHLW): a health certificate from the exporting country's government must be filed with the quarantine station, and rodents must come from a holding facility designated by that government. Animals bred in Japan can be sold and kept without notification. Never release captive animals into the wild.

Mainly seed-eating omnivore: conifer seeds, fungi, buds and fruit
An arboreal squirrel of dense canopy. Use a tall cage with branches and shelves arranged in three dimensions, and a nest box placed high.
Mainly conifer seeds, plus fungi, buds, flowers, fruit, sap and insects. Avoid a seed-only diet, and check hidden caches for spoilage.
Intensely territorial and solitary, so keeping more than one invites fights. Mainly diurnal and especially active in autumn.
A cold-climate species; wild animals have been reported to stop activity entirely at −31.6°C. Heat data are scarce, so air-condition the room through a Japanese summer.
As a squirrel it needs a species-name certificate on import, and imports fall under the animal import notification system. Its genus is not a designated or uncategorized invasive taxon.
Alien squirrels such as Pallas's squirrel are already a problem in Japan. Never release captive animals into the wild.
Advanced. This is an advanced-level species. It requires specialized equipment and advanced husbandry skills with precise environmental control.
