Continuing immature bird on the beach side, right off the point to the west of the beach building. The things that indicate that this is Trumpeter instead of Tundra (for me) include the large amount of black skin between the bill and the eyes (this would look like a thin line on TUSW), the large size of the bill (TUSW has a smaller bill; I know this kind of size judgement can be hard to prove when there's nothing to compare it to), and the "V" shape that can be seen above the bill when looking at the face head-on (TUSW would look like a "U" in this area).
