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.

Appearance:

Resembles a big, black Curlew, but can only be confused with Bald Ibis. Differs from this by longer, slender neck, rounded and feathered head, long legs (trailing in flight) and heavier bill. Bare parts greyish, not red. Adults with glossy green wings. Immatures and birds in winter plumage with white-speckled head and neck. Head and legs droops slightly below horizontal plane in flight, leaving a "hunched" impression. Wing beats faster than herons of same size. May glide longer distances, but does not soar like Bald Ibis. Flight formation loose, diagonal or in single file with undulating movements.

Sound:

Generally silent away from breeding ground. Dry, crow-like "garr garr", may be heard occasionally in flight. At breeding ground various guttural grunts, and piping, hissing sounds.
