Appearance:

Adult breeding birds unmistakable. White mask, warm rufous brown throat and underparts. Bill noticeably heavier than in Red-necked Phalarope in all plumages and and ages. Female more brightly coloured than male (reversed dimorphism). 1st winter birds differs from Red-necked in white fore-crown, while fresh juveniles have less contrasting markings on back. Both mentioned characters are often difficult, or impossible to use at a distance. With experience and practise, one can use the powerful flight and more stocky build as field marks.

Sound:

Flight-call a short and sharp, Coot-like "kit". Cleaner and higher pitched than Red-necked Phalarope. Display sound a rolling cooing, at stable pitch. Other calls: a hissing like the squeezing of a rubber duck, rising quickly in pitch and ending abruptly.
