A friend told me where I could see Tundra Swans, which had dropped by local fields. I took a drive out to see them and, sure enough, there was a field full of them! The photo shows only a portion of them, which was very large. I hadn't been aware that these swans stop over here on their migration route. I am not sure about the identity of the smaller black birds among them.

Note what 'ducks.org' http://www.ducks.org/hunting/waterfowl-id/tundra-swan) has to say about the Tundra Swan - "Tundra swans winter mainly along the Pacific and Atlantic coasts of North America, from southern British Columbia to California and from New Jersey to South Carolina."

Describing the Tundra Swan, the same source says, " Average length: 51.5 inches, Average weight: 13.9 lbs." So it is a pretty large bird.

Tundra Swan Description

"The plumage of adult tundra swans is completely white, though their heads and necks are often stained a rusty color from ferrous minerals encountered in marsh soils during feeding. The bill is black and often has a yellow spot at the base. The legs and feet are black and the iris is dark brown. Both sexes are identical in appearance, but males typically are larger. The tundra swan is smaller than the trumpeter swan, but it is difficult to separate them in the field. The tundra swan's call is high-pitched and reminiscent of snow geese, while the trumpeter swan's call is more vociferous and has been likened to the sound of a French horn."
