Fledge is Imminent

The drama has heightened at the White Breasted Nuthatch nest box.  After weeks of nesting activity, I think the actual fledge is just about to occur, or may have already done so!  This afternoon I saw both birds of the pair outside the box.  But they were both acting cagey: perhaps they're trying to lure out youngsters.  It is certainly time.  Given my schedule it won't be possible to watch what goes on in the next day or two.  But I can watch the feeders.  Young nuthatches will be introduced to the suet feeder for certain.  It should be interesting!  Will this be my first sighted juvenile species of 2012?
