Many species of waterfowl spend at least part of their lives in the wetlands of Missouri. Most duck species nest elsewhere and migrate through Missouri in fall and winter, but several species of dabbling ducks (mallards and blue-winged teal, for example) are known to nest here in rather low numbers. The wood duck and hooded merganser, both cavity nesters, are regular nesters in Missouri. Of the geese species, only one – the Canada goose – nests with any regularity in Missouri. This section focuses on food and habitat requirements for fall-migrating waterfowl.
