Such a cutie! I had a rather charmed encounter with this little critter back in August. I hiked into a talus field near the top of Trail Ridge Road in Rocky Mountain National Park hoping to catch images of some of the Pika as they scurried about. This particular one proved to be highly entertaining.
It was quite tolerant of me, approaching at times within a foot of me, sometimes pausing to check me out and make sure I meant no harm but largely going about its busy work. This afforded me the opportunity to get some great captures, including this one as it cleaned up after having a morning snack.
