. . . in the eternal duel of Dog and Fox.
And that duel usually occurs around 2 a.m., when M. and I are soundly sleeping with the bedroom window open.
Evidently the foxes think, "Let's go annoy those dogs." And so they bark (.wav file). It sounds as though they are only about 20 yards away.
And the dogs go berserk, baying at the window, running to the front door ("Let me out! I'll get that fox!").
After fifteen minutes, everyone settles down again--until the next night.
