English: Tundra Swan, Bewick’s Swan
Russian: Малая лебедь
German: Zwergschwan
French: Cygne de Bewick
Mongolian: Гунгар хун
Japanese: コハクチョウ (Ko-hakucho)

Body length: 115-127 cm
Wing span: 170-195 cm

Habitat: Breeds on far NE tundras by the Arctic Ocean. Winters in NW Europe. 

Identification: Very large. A smaller version of Whooper Swan, with proportionately slightly shorter neck, bigger head and more compact body and bill; these difference often difficult to appreciate when observing single birds. Safest separation by pattern of bill, Tundra having slightly less yellow than black, the yellow generally a square or rounded patch (diagnostic), rarely more wedge shaped (recalling Whooper, but yellow not reaching in front of nostril, and black around gape more solid). Also, with experience, voice is good clue.

Variation: Very rarely N American vagrants occur, distinguished by practically all-back bill (only a tiny yellow patch in front of eye).

• Juvenile: Greyish (often a shade darker than Whooper). Bill pattern of adult discernible (black of adult is pink, yellow is off-white).
