Upper Sunrise, American R. Pkwy.
A Fox Squirrel (Sciurus niger), photographed at Elk Grove Regional Park in Elk Grove, CA. Note the fair amount of orange in the tail and the pale orange/tan fringe of fur outlining its otherwise white underparts, its rather dense and bushy tail, and its rather stocky build, which all distinguish it from the somewhat similar Eastern Gray Squirrel (Sciurus carolinensis).
