|Observer’s Previous Acquaintance With This or Similar Species|
Inexperienced with Trumpeter Swan though have seen many Tundra and Mute Swans.
|I certify that that attachments included with this report were captured during this observation event.|
|Description of Habitat|
Mostly flooded marsh with some vegetation visible including cattails; fair amount of ice cover. Bird was loosely associating with larger race of Canada Geese (Branta canadensis). Scattered Mallards (Anas platyrhynchos) and American Black Ducks (Anas rubripes) were also in the vicinity.
This bird preened, stood on the ice, swam around, fed by tipping up, and slept on the ice. As it approached foraging Canada Geese, the geese quickly relinquished their feeding spots.
|Description of Vocalizations|
None heard, though bird could be seen opening and closing its bill at a distance presumably to vocalize.
