Appearance:

Medium sized diving duck. Male with rufous brown head and pale grey body. Female indistinctly coloured in grey and brown, with diffuse head markings. Easiest identified by fairly distinct head profile; long bill continuous with sloping forehead, ending in peaked crown (both sexes). Bulky body and short neck. Both sexes with long, pale grey wing-bars. Juveniles like female, except body warmer brown.

Sound:

Female: a coarse "ahrrrrrrr-ahrrrrr-ahrrrr" with a vibrating quality. Male courting call a pleasant, drawn out, nasal whistle "tweeeeep", rising in pitch, often followed by a falling "puuuh" (e.g a long disyllabic tweeepuuuuuuh). Also a sharper "ki-ki-ki" or "ki-ki-kiko".

Appearance:

Breeding plumaged adults with streamers unmistakable (streamers comprising two thirds of total tail length). Adult plumage shows less variation than in other skuas. No hint of breast band, and transition between pale belly and darker vent very diffuse. No white patches at base of primaries of underwing in adults. Juveniles easily confused with juvenile Arctic Skua, but are more slender. Wings narrower and primaries and tail longer. Juvenile Arctic Skua shows white patches at base of primaries on both sides of wings, juvenile Long-tailed only on underwing, and on first few primaries of upper. Barred rump and tail coverts in juveniles. Flight elegant and buoyant.

Sound:

Calls sharp and less full-bodied than Arctic Skua, and not so mewing. Short, double-accented "kew-wev" or short "kerk" in agitation. Also a long drawn-out "keeeeaah", resembling both Arctic Skua and Common Gull.
