The Red squirrel (Tamiasciurus hudsonicus) is pretty common in the Great Smoky Mountains. This one, on the Rainbow Falls trail up the side of Mount LeConte, was kind enough to pose for us.
The classic identification marks are all visible here; reddish-brown back, white belly, white rings around eyes. Some will have ear tufts in season, though this one has only the faintest wisps of tufts.
Early March 2008.
