Aha, this little guy is a feisty one indeed. His proper common name is Clark's Nutcracker, but deary me he is well known to many as the Camp Robber. He gains that nickname honestly. This last summer one swiped a strip of bacon from our campground table and took off with it, and I have reason to believe that they are also fond of grapes. I know from experience and lost grapes. Even in the winter they hang about to see what they can get their beaks on.
The California Calico --hey, a double C--ranges obviously beyond California.
This chipmunk stopped to enjoy a snack that was not actually provided by campers. At camp, his cousins were found gazing hungrily at our jar of trail mix, trying to figure out its method of entry.
