Alarmed

A Townsend’s chipmunk whips its tail back and forth. I had been watching it for a while and it didn’t seem bothered by my presence, so I didn’t think it was upset with me, but on the other hand I couldn’t see anything in the vicinity that would give it pause. I think it was testing me though, as when I didn’t move it ran down to collect some of the dead grasshoppers around me that had gotten trampled on the trail by hikers earlier in the day.
