Mariton – Bluebirds Nesting

A pair of Bluebirds has finally started nesting at Mariton.  I have been faithfully monitoring the nest boxes for over a month.  This is the average start of nesting activity, based on my records.  Considering the weather, I am a little surprised that they started a nest this early (first nests have appeared as late as April 22).  The nest is not quite finished.  Hopefully the weather warms up and dries out a little before the female starts laying eggs.
