Notes from 2017
ACLT: Plan on adding a number of new boxes at Horse Swamp for the 2018 season.
Battle Creek: Prothonotary Warblers like the boxes; their broods were larger than those in the PW boxes.
Calvert Cliffs: The water level in Grey's Creek continues to be very low.
Will have to move at least 2 boxes on Thomas Creek because of Phragmites.
Cove Farm: Starlings invaded one of the boxes; could not confirm hatching.
CPNHT: 1st full yr. Wasps were an issue; will soap boxes in the spring to see if that deter the wasps.
Flag Ponds: Multiple double broods this year.
Ward Farm: Adding Prothonotary Warblers boxes. Will have to keep an eye on the warblers use of the Wood Duck Boxes.
