Appearance:

Adults with white front of head reaching crown, black markings on belly and obvious, swollen yellow eye-ring. Juveniles lacks white forehead and black markings on belly. The yellow eye-ring is also less noticeable. Note that White-fronted Goose may also show faint eye-ring, limited belly-markings and extended white front to head. Leaves a more "pure" impression than White-fronted, with evenly coloured plumage, rounded body, short neck, short bill and steep forehead. Primaries are longer than in other geese, and may extend past tail.

Sound:

Contact call a characteristic, trisyllabic, yelping "ka-dyl-lyt". First syllable often with a goose-like timbre, and second and third a continuous clearer sound, with a rapid lowering of pitch between syllables. Much higher pitched than other grey geese.
