Each year cooperators visit sample wetlands during two survey periods, collecting data on observed waterfowl and pond conditions. Along with ground counts, aerial photography of sample areas is collected annually, capturing habitat conditions. My objective was to assess the influence of local and landscape factors on duck pair densities. Local …
