The "striped collector"

 

Eastern Chipmunk (Tamias striatus) eating an acorn in Alstead, New Hampshire, on 27 September 2015.

 

Although we knew "striatus" means striped, we weren't sure about "Tamias."  After doing some research, it sounds like Tamias means "collector" or "keeper" — an appropriate name for an animal that stores nuts and seeds underground for the winter. 

P.S.  I posted a photo of a Sonoma Chipmunk (at Point Reyes) on 27 May 2012.
