The west porch pillars are hollow, with ventilation holes cut about halfway up.  For the last few days, a Downy woodpecker has been happily working on the inside of the pillar directly outside my window.  He or she seems to be intent on enlarging the hole, as it is currently a bit of squeeze to get in.  It seems to be their mid-morning job, for an hour or two.  It just might drive me nuts.
