Appearance:

Large and heavy skua with broad wings and short tail. The white patches at base of primaries are more striking than in the other skuas, and are visible both on upper and underside of wings. Size comparable to Herring Gull, but build more compact. Seemingly black at a distance, but white wing-patches usually visible. Confusion with juvenile Pomarine Skua possible, but body is heavier (not just the chest), wings rounder, bill longer, neck thicker and tail shorter.

Sound:

Heard mostly at breeding ground. Short, and dry "kek", when agitated. Also a nasal, slightly mewing "kew".

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.
