Wikipedia Abstract

Richardson's ground squirrel (Urocitellus richardsonii), also known as the Dakrat, or Flickertail, is a North American ground squirrel in the genus Urocitellus. Like a number of other ground squirrels, they are sometimes called gophers, though this name belongs more strictly to the pocket gophers of family Geomyidae.
