Engaged

It appears that our bluebird couple has committed.  Within 12 hours of posting the blip of our lonely male  several days ago, a nest was started in the nest box.  Our fellow keeps watch over the box, chasing away the curious chickadees that occasionally stop by and the gal is busy collecting white pine needles for her nest.  Each day the nest has grown and she was still busy at work on it today.   Nest building last 2-6 days. Today is day 4.
