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.

Appearance:

A long-tailed and relatively long-winged Locustella, with olive-brown plumage and pale belly. Conspicuously broad, rounded tail, and substantial vent. Under tail coverts brown with with prominent pale fringes, and almost reaches tail tip. Faintly streaked throat and breast. Rump and tail warmer brown than back. Faint and short supercilium and pale eye-ring. First long primary with pale outer web, and a slight curve. Song-posts often more exposed than Grasshopper Warbler.

Sound:

Song an insectlike, buzzing like Grasshopper and Savi's Warbler, but easily distinguished from those by it's distinct steam locomotive-like rhythm. About 8 accents per second. Perhaps easier to confuse with certain species of ground crickets or cicadas than it's congeners. Contact call a sharp "tsikk-tsikk", similar to Savi's Warbler.
