Trumpeter Swan Trumpeter Swan
The Trumpeter Swan is the largest of all swans. It comes from North America (equivalent of Eurasian Whooper Swan, but a bit larger; similar trumpeting sound). It has a fully black beak.
The head and body of the adult swan is all white, but those shown here with some greyish-brown plumage are juveniles at about a year old.
