There are quite a number of simple observational studies you could do. From the very simple what species of waterfowl over winter in my area. Do waterfowl move their nests in preparation for the winter? More complicated might be questions about diet changes from summer to winter, Do waterfowl abandon small lakes that tend to freeze over? Perhaps the easiest is to just do a population study, how many, what species, what habitat.
