Eastern Gray Squirrel

The backyard plotter, burying nuts in autumn and faking burials to fool thieves watching from the trees.

Least Concern

Sciurus carolinensis

Overview

The eastern gray squirrel is the default squirrel of American parks and suburbs, agile, bold, and endlessly entertaining as it raids bird feeders and zigzags across roads. Native to the eastern US, it has been introduced to the UK and parts of the West Coast, where it thrives.

Watch one in autumn and you'll see the full deception routine: bury a nut, pretend to bury another while holding the real one in its mouth, all while a neighbour watches from a fence. A common discovery, but one with real character.

Habitat

  • Deciduous woodland
  • Parks
  • Suburbs
  • Mixed forest

Eastern gray squirrels live in deciduous and mixed woodland, parks, and leafy suburbs across the eastern and midwestern United States. They nest in tree cavities or leaf dreys and depend on oak, hickory, and walnut for autumn mast.
