Book Description
The International Joint Commission, which is charged with improving the environmental quality of the Great Lakes, has designated for specific remedial actions 43 Areas of Concern (AOCs) where the aquatic environment has been most severely degraded. This report summarizes information gathered over the past 28 years on the amount and timing of use by waterfowl in seven of those 43 AOCs (those AOCs in Canada along the southern Great Lakes which contain important habitat for staging waterfowl). It also provides comparable information on other important areas along the Great Lakes shore from the Bruce Peninsula to the Quebec border. In addition, a brief description of the nutritional and other habitat requirements of staging waterfowl is included. Information presented include habitat use by taxonomic group, overall trends, waterfowl counts by group, and survey sampling dates.

Book Description
Michigan is located at the center of the Great Lakes Region that supports more than 3 million autumn waterfowl migrants annually. Beginning in the 1940s and 1950s, the Michigan Department of Natural Resources (DNR) and the United States Fish and Wildlife Service (USFWS, hereafter) began consolidating large wetland complexes in Michigan's Lower Peninsula. Since the 1970s, Michigan DNR and USFWS staff have maintained records on autumn waterfowl use, as well as harvest associated with managed hunting programs. I analyzed archived count data in conjunction with various measures of climate, weather, hydrology, and stock. I determined that the total number of ducks that these areas support in a given year have largely been in decline since the early 1990s. I analyzed timings of species-specific waterfowl abundance on areas and observed trends in seasonal timings. Finally, I measured changes in relative abundance of mallards as a function of weather variable. In my second chapter, I determined the influence of time of day, season progression, habitat type, and disturbance levels on a measure of habitat selection, using a novel method for surveying waterfowl. In my third chapter, I used archived data dating back to the 1970s to evaluate annual and seasonal measures of hunting program success. These results provide insights on multiple levels of waterfowl use and associated recreation and will help inform future management on the study sites.

Book Description
The author evaluated diet and food selection of 5 species of spring-migrating female waterfowl including 3 dabbling ducks (Blue-winged teal, Anas discors, Mallard, Anas platyrhynchos, Gadwall, Anas strepera) and 2 diving ducks (Lesser Scaup, Aythya affinis, and Ring-necked duck, Aythya collaris). Diet was evaluated with regards to the proportion of invertebrates and seeds consumed, and compared to forage availability data collected in habitats available to them at 6 study locations throughout the Upper Mississippi River and Great Lakes Region. The author found latitude (i.e., stage of migration), longitude, food availability, and date all influenced the diet of spring migrating waterfowl, with some factors having a stronger influence than others. The author observed differing diet trends with regard to foraging guild (e.g., dabbling and diving ducks), as each foraging guild was represented by 1 species that was heavily dependant on invertebrates (dabbling duck - Blue-winged teal; diving duck - Lesser scaup) and 1 species that was heavily dependant on seeds (dabbling duck - Mallard; diving duck - Ring-necked duck). The proportion of invertebrate foods in the diet increased throughout spring for all species of waterfowl, suggesting the importance of invertebrate food sources during spring staging. Data from this study provides valuable information to habitat managers and conservationists wishing to improve spring habitat conditions for migrating waterfowl, which likely influences waterfowl productivity.
