I built a WD nest last year that resemble yours Ski. I have had Whistling Ducks in there the last 2 springs. It is comical to watch them get in the hole. They do fly right at the hole then grab the hole with their webbed feet and pull themselves in head-first. I did shoot a 64" mocassin out of the house the first spring. I think it was egg hunting.

20 acres of trees & 3/4 acre pond.
