Panther Lake Prothonotary Warbler boxes

I checked the Prothonotary Warbler boxes at Panther Lake near Fuquay Varina, NC. last week. It is not a very big lake so I only have 5 boxes on the lake. All 5 boxes had nests in them this year. The boxes are mounted on metal conduit poles over water about 5 feet from land.
I am planning on putting up 4 more boxes on Panther Lake.
