Appearance:

A small, elegant diving duck with highly variable looks depending on sex and time of year. Several moults with transitional plumages. Males with long, pointed tail and pink banded bill in most plumages. Females with grey bill. In all plumages note: small head, steep forehead and short bill with high base. Wings always all dark (also underside). Only diving duck with dark wings and light body. Flies with wings hardly raised above horizontal plane on upstroke.

Sound:

Very vocal and distinct. Male: a pleasant resonant melodic "ahh-aaooee" in a yodeling, breaking triad. Starting with an accented first note (ahh), then gliding from first through second and third note (-aaoooeee). Far carrying. Female: calls often, but less musical and distinct than male.

Appearance:

Fairly large warbler with long tail, giving the whole bird an elongated look. Tertials, secondaries and coverts with rufous fringes in contrast to greyish brown back. Underparts pale with buff flanks. Outer tail feathers white. Steep forehead and white throat. Males with slate grey head.

Sound:

Variable. Usually recognized by fairly concise phrase, usually with three ascending and descending parts. Often ends with more indistinct mimicry, or subsong. May omit characteristic phrase and sing more cryptic for periods of time, and may be more difficult to identify. Warning call a harsh, drawn "weeet", usually with accented ending, sometimes rising abruptly in pitch.
