I built two Wood duck boxes from the outside cut of cypress tree. This leaves the outside skin of the Cypress tree, my thoughts were, they would be more natural looking. Added onto a post and I covered the post with 4" pvc. Set them along the water edge. This past spring I watched a couple of Woodies look them over closely but never saw them go into the boxes. This last early Duck season, I watched and counted 53 wood ducks land on the pond one evening. They arrived in groups of 9 or so. I have 3 TH feeders @ the pond and these Woodies would go from feeder to feeder, racing to see who get to the feeder first as the feeders would go off. So we will wait and see this yr if any Wood ducks will take up home @ the pond. If they don't take to the boxes, I will do something different, just not sure what.
