Goshawk (Accipiter gentilis)
Parasitic Jaeger (Stercorarius parasiticus)
Bulky raptor with long tail and short, rounded wings. Small males may be difficult to separate from large Sparrowhawk females. Upperparts grey-brown, and underparts pale and barred or speckled. Male and female quite similar, but female larger. Juveniles browner than adults, with heavily speckled underparts. Supercilium prominent in both sexes. Bulkier belly and broader at base of tail than Sparrowhawk. Deep chest. Longer wings and longer secondaries gives more of a S-shape to trailing edge of wings. Slightly rounded tail-corners visible when soaring. Flight alternates series of wingbeats with short glides without loosing height.
Sound:Series of short "ke-ke-ke-ke-ke". More resonant, both sharper and deeper pitched than similar call of Sparrowhawk, and much slower. Also a wailing "peeeaaaaw"

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").
