Among points of distinction noted on a lone ad. Trumpeter Swan in December in nw. California (heard, photographed, and accepted by the state records committee) was that the bird's neck musculature seemed more developed, such that there was a shallow groove along the side of the neck. Tundra Swans in the same flock did not show this, or at least not to the extent of this individual.

A great resource for learning how to separate immature Tundra and Trumpeter Swans can be found at this link:

One year old Trumpeter Swans (birds in their second fall/winter) often have some gray on head and neck, and the featured photo may be of a one year old bird, rather than an adult.

Additionally, the shape of the feathering extending onto culmen is somewhat variable, and some Trumpeters will have that feathering appear somewhat rounded, while some Tundra Swans may show a bit of a point to this feathering. In immatures, this mark is even less accurate.

Also note that birds in their first fall/winter/spring have yellow feet and toe-webbing, a mark that some birds, I believe, carry into their second year.
