I visited my parents in Sumter, SC in January. Apparently, this small town is home to the only public park in the United States to feature all swan species. While I was there I managed to capture quite a few of them including:
Black Swan
Trumpeter Swan
Black-necked Swan
Mute Swan
Bewick's Swan
Whooper Swan
There were also a fair number of Canadian Geese, Wood Ducks and Mallards.
