   Note: The black or silver-gray fox is a variety of the
         American red fox, producing a fur of great value; the
         cross-gray and woods-gray foxes are other varieties of
         the same species, of less value. The common foxes of
         Europe and America are very similar; both are

         birds, poultry, and various small animals.
