Firecrest (Regulus ignicapilla)
Long-tailed Jaeger (Stercorarius longicaudus)
Distinct head markings, with black eye-stripe contrasting with broad, white supercilium. Top of head yellow (female), or orange (male), framed by black crown stripes. Characteristic orange shoulder patch, lacking in all confusion species. Immature is distinguished by present supercilium, other head markings absent.
Sound:Call: a thin "tsi tsi tsi" similar to Goldcrest, but not so sharp. Song: Similar in timbre to Goldcrest, but much more monotonous. A slow crescendo of short "tze" sounds in a phrase rising slightly in pitch, without the repeated arpeggiated movements of goldcrest.

CCBreeding 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.
