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.

Appearance:

Slender and elegant harrier, with narrow wings and four "fingers". Adult male easily recognized by very pale grey and white plumage, with diagnostic wedge-shaped, black wing-tips (outermost primary grey). Female and immature birds often difficult to tell from Montagu's Harrier and Hen Harrier. Adult female differs from Montagu's by lack of dark band on upper wing, and by diffuse, sooty inner underwing. Pale bands do not reach wingpit, and under coverts are darker. Differs from female Hen Harrier by noticeably slimmer wings (both hand and arm) and only 4 fingers (but beware moulting Hen Harriers). Immature similar to Montagu's with unstreaked, rufous underparts. Differs in pale tips of inner primaries, and dark half-collar and pale "boa".

Sound:

Some calls similar to Montagu's and Hen Harrier, but display call quite diagnostic. A thin, vibrating trill "peerrrrrrrr".
