The lack of a yellow bill spot on the adult argues against Tundra Swan, but I understand that this is not an absolute criteria. The straightness of the culmen and shape of the feather extension along the forehead are difficult to judge, especially at a distance. Perhaps most convincing was the amount of darkness on the immature. Tundra Swans are said to be quite white on the back and wings by spring. The size of the bill on the immature was also quite impressive. The date is a bit early for Tundra Swan, but fine for Trumpeter. | The original documentation form event lasted from 14:30:00/14:45:00.
