Addled Doves

I believe my past posts on Mourning Doves have left the impression that these birds are a breed apart.  Far apart.  We most often experienced the "Cup-A-Joe" effect as stupefied Doves sit at the safflower feeder like coffee house junkies.  This spring I have even seen evidence that the Addled Ones can't get their act together on reproduction.  We've seen a pair billing and attempting...something for an awful lot of days in April and May.  They're not there yet.  Is it the safflower? or is it Dove-nature to be the dimmest bulb in the barn?
