Chipmunk

We don't often see chipmunks but every once in awhile one shows up at the platform feeder.  I think it's a Townsend's chipmunk (Tamias townsendii).  In back of our house is 120 acres of park land composed of typical western Washington lowland forest - western hemlock, western red cedar, douglas fir, bigleaf maple (some huge), and a few alder that are past their prime.
