二名法 Sciurus carolinensisGmelin, 1788 灰松鼠（学名：Sciurus carolinensis）是一種原生於美國東部及中西部以及加拿大东部省份的松鼠族，但今日是歐洲的入侵種。灰松鼠是一种多产且适应性很强的松鼠，後來美國西部也繁殖起来。灰松鼠被引入到英国，成為入侵物種，對當地原生的歐亞紅松鼠構成威脅。爱尔兰东部的一些郡的欧亚红松鼠也受到威胁，但是欧亚红松鼠在南部和西部的郡仍然很常见。[1]意大利也有发生入侵的可能。國際自然保護聯盟物種存續委員會的入侵物種專家小組（ISSG）列為[世界百大外來入侵種]。描述如其名称所示，灰松鼠的皮毛主要为灰色，但是也有略带红色。其腹部为白色，尾巴很大且多毛。在城市里，由于威胁减少，常常可以看到白色或黑色的灰松鼠。在某些区域，如加拿大东南部，几乎全黑的灰松鼠有一定规模。同时也有一些变种，包括尾巴为黑色的品种，以及毛皮为黑色但尾巴为白色的品种。其头和身体长度为23-30厘米，尾巴为19-25厘米，成年灰松鼠体重为400-600克。[2] 参考资料 ^ Carey, M., Hamilton, G., Poole, A., and Lawton, C..

Article

The eastern gray squirrel (Sciurus carolinensis), spelled as grey squirrel outside of the United States, is a species of tree squirrel in the genus Sciurus. It is native to eastern North America, where it is the most prodigious and ecologically essential natural forest regenerator. Widely introduced to certain places around the world, the eastern gray squirrel in Europe, in particular, is regarded as an invasive species.

In Europe, Sciurus carolinensis is included (since 2016) in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.
