Nice work, Jason!
I've been doing what you are doing going on 25 years now and have had tremendous success with the re-establishment of the wood duck. I've posted a link to some info that I handed out and/or referenced to folks interested in building and erecting their own boxes. I also put them up as a part of my Wildlife Habitat Service business when I was active. I've probably built and erected over 500 boxes over the years. It's mighty rewarding to be able to check that hen on the nest and later see those little fuzz balls pop out and follow mamma off on the new great adventure.
Feel free to use and share any of this info. Please insist that your folks erect a predator guard on all boxes they put up. If not, they are just feeding the snakes, coons, and other predators. Also, that entrance hole doesn't need to be any bigger than a 4 inch wide, 3 inches tall hole. Any bigger promotes owls, starlings, etc.
Enjoyed reading your article!http://s766.photobucket.com/user/tenfingergrip/library/Wood%20Duck%20Boxes
