It is absolutely ok to ask for id help on OBOL. I think most folks would
appreciate you making an effort to id the bird so informative help can be
given, So it is great that you stated what you thought and why. The bill
shape is a bit tougher to differentiate on young swan, but the skin on
Trumpeter reaches back and touches the eye, Tundra Swan has the skin end
right in front of eye. Trumpeter juveniles usually have black at base of
bill, Tundra juvenile has pink reach back farther into base of bill and
often show white where the yellow will develop. Not clear here of course,
but a Trumpeter Swan is a massive bird compared to a Tundra, standing next
to each other it is almost like a goose to a duck. So I say Tundra.
