This pair of Siskiyou Chipmunks was seen on our National Grasslands and we really do not see to many there.
We have the Golden-Mantled Ground squirrel who looks similar, but does not have the stripes into the face.These are very loud little things and if they were not so loud I may not have even seen them on this log! Here in Central Oregon we have a way of having MANY rodents who cause damage to the land, however these Siskiyou Chipmunks live in trees and the like.
There is a couple here, the one on the left is just chatting up a storm! The one on the right, well that one seams to be listening but soon leaves. The chatty one you can see it wondering why it is by itself.
