Eastern Gray Squirrel

Sciurus carolinensis

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The eastern grey squirrel comes originally from eastern North America, where it occupies mature woodland of oak, hickory and beech. Introduced into Great Britain and Ireland in the late nineteenth century, and later into Italy and South Africa, it has become one of the most problematic invasive species in Europe. It stores thousands of nuts every autumn in individual caches scattered across its territory and recovers them later by combining smell with a remarkable spatial memory. It is diurnal, highly adaptable and abundant in urban parks.

Fun facts

  • inteligenciaIt will pretend to bury food in a false cache if it senses another squirrel watching, a piece of deception known as deceptive caching.
  • In Great Britain it has almost entirely displaced the Eurasian red squirrel: as well as competing for food it carries a parapoxvirus that does not affect it but that is lethal to the native species.
  • It practises deceptive caching: if it notices another squirrel watching, it digs a hole and pretends to deposit the nut, keeping it in its mouth to hide somewhere else.
