觀察細節
Initially thought the adult with the Straight bill, totally black, plus the Immature suggesting V shape at top of bill confirmed trumpeter. Lack of other confirming points, overall size of all 5 being the same, and vocalization that was not trumpeter makes tundra more likely. An interesting feature noted in Sibley is the shape of the back, more evenly rounded, unlike all of these.
