ABSTRACT: U.S. Fish and Wildlife Biologists Gil Gigstead and Milford Smith first utilized wood duck (Aix sponsa) nesting boxes at Chautauqua National Wildlife Refuge in 1937.  These boxes sought to imitate the declining number of natural tree cavities in old growth forest that wood ducks and hooded mergansers (Lophodytes cucullatus) use for rearing their young.  In the George W. Mead Wildlife Area there are 120-130 wood duck boxes.  These boxes are permanent additions to the landscape and are only taken down if parts need to be replaced.  Each winter the boxes are cleaned out, and data on species utilization, nest success, box height, distance from water, and box opening orientation is collected.  We then use AIC software to analyze this data and determine the model of best fit to see if there is a correlation between one of these factors and nest selection behavior in cavity nesting waterfowl.  Over a 13-year period, our data showed that less than half of the boxes we looked at had been used by cavity nesting waterfowl. We will present our findings at the Midwest Fish & Wildlife Conference.
