White-tailed Eagle (Haliaeetus albicilla)
Parasitic Jaeger (Stercorarius parasiticus)
Diagnostic flight profile with rectangular, uniformly broad and deeply fingered wings. Long neck and short, wedge-shaped tail. Bill very heavy and tarsus unfeathered. Adults with pale, yellowish head and white tail. Juveniles uniformly brown with dark tail. Females bigger than males. Flight pattern: Long sequences of shallow wing-beats, and only limited glides (as opposed to Golden Eagle).
Sound:A sharp high-pitched clear "klyytt klyytt klyytt klyytt" is often heard. Uttered with some variation in pitch and timbre. Sometimes more raucous and not so high pitched.

Dark, pale and intermediate morphs. Pale birds more common in northern parts of species range, darker morphs more common further south. Elongated middle tail feathers (projection comprising about half the total tail length), but not as long as in adult Long-tailed skua. White patches at base of primaries, both on upper and underside of wings. Dark morph chocolate brown with darker hood. Pale morph with white throat and belly and incomplete breast band. Relatively marked transition from pale belly to dark vent (as opposed to Long-tailed). Size close to Common Gull. Flight powerful, elegant and falcon-like. Juveniles with short but pointed middle tail-feathers. Confusion with other juvenile skuas very likely. Differs from Long-tailed in prominent white base of most primaries on upper side of wing (not just the first few feathers). Lacks the double white patch of Pomarine Skua's underwing, and shows less contrast between back and rump. Wings broader than Long-tailed but narrower than Pomarine. Approximately equal to distance from wing rear edge to tail-tip (projections excluded).
Sound:Mostly heard at breeding ground. Most characteristic call is a mewing, kittiwake-like "aeeeee-ah". First syllable drawn-out and rising in pitch, and followed by a deeper conclusive second syllable "ah". Lacks the introductory double accent of Kittiwakes ("kitti-wake").
