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.
