Wikipedia:”The Delmarva fox squirrel also known as the eastern fox squirrel or Sciurus niger cinereus, is an endangered subspecies of fox squirrel.[2] Its historical range included the Delmarva Peninsula, southeastern Pennsylvania and southern New Jersey, but its natural occurrence is now limited to parts of the Eastern Shore of Maryland and Virginia.[3] In these areas the Delmarva fox squirrel’s habitat has been degraded and its survivability rates have decreased. It has, however, been successfully reintroduced in other parts of its historical range.”
