              the family . . . is alternately known as the
              nightjars derived from the "churring" sounds of
              several species -- "jarring" the night air, or
              goatsuckers, a nonsense name that should be
              discontinued as it has its origin in the
              preposterous myth that the birds sucked the milk
              of nanny goats until they were dry. --terence
