About the Eastern Gray Squirrel#
Sciurus carolinensis, common name eastern gray squirrel or grey squirrel depending on region, is a 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. The eastern grey squirrel in Europe is regarded as an invasive species.

Field-craft tips#
- Great subjects for learning — confiding in parks.
- Get your lens at the animal's eye level.
- Get down to eye level; a long lens with close focus (or an extension tube) helps with small subjects.
- Sightings peak in April and September, which is when you'll have the most chances.
Ethics#
- The welfare of the animal comes first: if it changes its behaviour because of you, you are too close.
- Stay on trails, respect closures around nests, leks, dens and haul-outs.
- Avoid playback and baiting in sensitive seasons; never bait predators.
- Don't share precise locations of rare, nesting or roosting animals publicly.
