Veliki labud Cygnus cygnus

Immense swan of frigid northern regions; breeds on the tundra, taiga, and steppe and winters in marshy lakes and wetlands, often in wild areas. Fairly straight neck, short tail, and sloping bill distinct from Mute Swan; told from smaller Bewick’s (Tundra) Swan by larger and pointed yellow patch at base of bill, also lower-pitched and more bugling calls. Juvenile often dingier through first winter than juvenile Bewick’s; juveniles of both usually found with adults as family groups.
