There were lots of birds around.  Just not a lot moving.  We did a good bit of scouting in the afternoon during the slow part.  As we motored around we got plenty of ducks up and moving.  Was a beautiful day to be out on the water.  There were a lot of planes flying.  More than I ever recall hearing or seeing.
 
My son and I saw some greenwings, a couple of pintail, one widgeon, and plenty of blacks.  Also had a couple of flocks of Canadas in the marsh behind us.  I think I saw a flock of Brant flying.  I estimate the flock was about 150-200 birds.  They were well south of us.  Initially they looked to be a formation flying like Canadas, then they bunched up too much and became too disorganized for me to believe they were Canadas.
