This winter we also saw a Bewick's Swan or tundra swan
on the whooper pond during the cold snap, sadly only for a couple of days.
Of the 40 species, there were nine species of shorebirds, seven dabbling ducks, five diving ducks, four waders, three gulls, and two "geese" (one was light geese, which includes Snow and Ross' Geese), in addition to Ruddy Duck (Oxyura jamaicensis), American Coot (Fulica americana), White Pelican (Pelecanus erythrorhynchus), Double-crested Cormorant (Phalacrocorax auritus), Tundra Swan
(Cygnus columbianus), Sandhill Crane, Caspian Tern (Hydroprogne caspia), and two species that could not be identified (one dabbling duck and one sandpiper).
From October 2013 to April 2014, the age structure of the Tundra Swan
was surveyed by point count method at 45 survey sites of Poyang Lake.
They are now considered to be a race of the tundra swan
, which also includes the whistling swan of North America.
Bewick's Swan, now more widely known as the Tundra Swan
, is a large, long-necked, pure white species of waterfowl.
When I look back on the week, we saw a fine mix of bufflehead, green-wing teal, black duck, northern shoveler, ruddy ducks, hooded mergansers, blue-winged teal, bluebills, mallards, long-tailed ducks, common scoters, tundra swan
and Canada geese.
2,000 permits were available for this fall's tundra swan
hunt, with more than 5,000 hunters applying for permits.

There's nothing more beautiful than a tundra swan
in the snow.
This expansion into new areas has resulted in recent observations of an overlap of the breeding distribution with that of the smaller tundra swan
Cygnus columbianus in some areas.
