I can't tell from the photos which species this is, nor did I have the chance to get a good look at any other diagnostic features at the time, so unless someone can tell me which this is - and please, please do if you know - I'll just have to say it's one of the two.

Here are some more photos of various individuals:

#51 Douglas's Squirrel

Tamiasciurus douglasii
IUCN Redlist: Least Concern
Location: Mariposa Grove, Yosemite National Park, USA
Time: 1020 PDT June 30 2011

This one had me scratching my head for a bit. According to the guidebooks and other resources I've consulted, Douglas's squirrel has orange undersides and eye-ring. The western gray squirrel, Sciurus griseus, is the most similar species living in this area, but is quite different looking, and lacks the dark stripe on the side. Alternatively it could be a spruce squirrel (a regional form of the red squirrel, Tamiasciurus hudsonicus) a long way from home.

But then I checked out some photos on google images that people had identified as Douglas's squirrel that had white undersides and eye-rings. So maybe I'm still wrong, but at least I'm not alone
