Ducks, Geese, & Swans

Wisconsin’s water-world showcases an impressive collection of waterfowl that’ll make any bird enthusiast’s heart skip a beat.

You’ll discover three main groups of these aquatic athletes: ducks, geese, and swans.

Duck identification becomes easier once you understand the difference between dabbling ducks (like mallards) and diving species.

Wisconsin waterfowl includes over a dozen duck species Wisconsin birders can spot year-round, plus several goose species Wisconsin residents know well.

Waterfowl migration brings seasonal visitors, while some hardy species stick around all winter.

You’ll notice interesting nesting habits among different species – some prefer ground nests, others choose tree cavities.

Conservation efforts have helped populations recover from past declines.

Keep an eye out for hybrid waterfowl, which occasionally appear when different species interbreed.

These remarkable birds adapt to everything from urban ponds to remote wilderness lakes.

Mallard

You’ll easily spot male mallards by their glossy green heads and bright white collars – they’re like nature’s gentlemen in tuxedos. These iconic Wisconsin waterfowl are the duck equivalent of your friendly neighbor who adapts to any situation.
