Fox Squirrel. Sciurus niger cinereus. Rare. What is thought to 

 be an unusually large Red or Gray is often the Fox Squirrel. I have 

 never seen one in Groton, but they have undoubtedly lived here at 

 some time.

 where, especially in old stone-walls. 



Woodchuck. Arctomys monax. Common in fields.
