Trumpeter and Tundra Swans can be difficult to separate in the field when seen alone, distantly, or under other difficult circumstances. For some excellent ID tips, see David Sibley's swan ID notes.

Head comparison of juvenile Tundra (right- note very narrow lores) and adult Trumpeter Swans, Lake Ogalalla, Nebraska, 2/17/03. (Note the more concave upper bill profile and much thinner lores of the juvenile bird.) The juvenile isn't really as tall as the adult- it was just standing up in shallow water while the adult was still swimming. See more Tundra Swan shots here.

Comparison of juvenile Tundra and adult Trumpeter Swans, Lake Ogalalla, Nebraska, 2/17/03. (Note the difference in size between the two birds. By February, juvenile TRUS should be virtually as big as adults.) See more Tundra Swan shots here.

Nice look at the "V" shaped forehead/bill junction. The same feature on a Tundra Swan is much straighter, forming a gentle curve instead of the sharp point. ("Valmont" Trumpeter Swan, Boulder, Colorado, 2/1/03.)
