Description

Pine squirrels, Tamiasciurus species, are small tree squirrels with bushy tails. Along with members of the genus Sciurus, they are members of the Sciurini tribe.

The name Tamiasciurus comes from Greek wiktionary:ταμίας tamías ‘steward, dispenser’ and wiktionary:σκίουρος skíouros 'squirrel'.

The American red squirrel should not be confused with the Eurasian red squirrel (Sciurus vulgaris) — both are usually just referred to as the "red squirrel" in their home continents.

Pine squirrels rely on a variety of food sources including fungi, plants, arthropods and tree seed.^[4]
